Providing this parameter is necessary for TCP/IP connections. One of either `host` or `unix_sock` must be provided. The default is `localhost`. +- *database* - The name of the database instance to connect with. If `None` then the PostgreSQL server will assume the database name is the same as the username. If your server character encoding is not `ascii` or `utf8`, then you need to provide `database` as bytes, eg. `'my_db'.encode('EUC-JP')`. +- *port* - The TCP/IP port of the PostgreSQL server instance. This parameter defaults to `5432`, the registered common port of PostgreSQL TCP/IP servers. +- *password* - The user password to connect to the server with. This parameter is optional; if omitted and the database server requests password-based authentication, the connection will fail to open. If this parameter is provided but not requested by the server, no error will occur. If your server character encoding is not `ascii` or `utf8`, then you need to provide `password` as bytes, eg. `'my_password'.encode('EUC-JP')`. +- *source_address* - The source IP address which initiates the connection to the PostgreSQL server. The default is `None` which means that the operating system will choose the source address. +- *unix_sock* - The path to the UNIX socket to access the database through, for example, `'/tmp/.s.PGSQL.5432'`. One of either `host` or `unix_sock` must be provided. +- *ssl_context* - This governs SSL encryption for TCP/IP sockets. It can have four values: + - `None`, the default, meaning that an attempt will be made to connect over SSL, but if this is rejected by the server then pg8000 will fall back to using a plain socket. + - `True`, means use SSL with an `ssl.SSLContext` with the minimum of checks. + - `False`, means to not attempt to create an SSL socket. + - An instance of `ssl.SSLContext` which will be used to create the SSL connection. +- *timeout* - This is the time in seconds before the connection to the server will time out. The default is `None` which means no timeout. +- *tcp_keepalive* - If `True` then use [TCP keepalive](https://en.wikipedia.org/wiki/Keepalive#TCP_keepalive). The default is `True`. +- *application_name* - Sets the [application\_name](https://www.postgresql.org/docs/current/runtime-config-logging.html#GUC-APPLICATION-NAME). If your server character encoding is not `ascii` or `utf8`, then you need to provide values as bytes, eg. `'my_application_name'.encode('EUC-JP')`. The default is `None` which means that the server will set the application name. +- *replication* - Used to run in [streaming replication mode](https://www.postgresql.org/docs/current/protocol-replication.html). If your server character encoding is not `ascii` or `utf8`, then you need to provide values as bytes, eg. `'database'.encode('EUC-JP')`. +- *sock* - A socket-like object to use for the connection. For example, `sock` could be a plain `socket.socket`, or it could represent an SSH tunnel or perhaps an `ssl.SSLSocket` to an SSL proxy. If an `ssl.SSLContext` is provided, then it will be used to attempt to create an SSL socket from the provided socket. + +### pg8000.native.Connection.notifications + +A deque of server-side +[notifications](https://www.postgresql.org/docs/current/sql-notify.html) received by +this database connection (via the `LISTEN` / `NOTIFY` PostgreSQL commands).

For +pg8000, the threadsafety value is 1, meaning that threads may share the module but not +connections. + + +#### pg8000.dbapi.paramstyle + +String property stating the type of parameter marker formatting expected by +the interface. This value defaults to "format", in which parameters are +marked in this format: "WHERE name=%s". + +As an extension to the DBAPI specification, this value is not constant; it can be +changed to any of the following values: + +- *qmark* - Question mark style, eg. `WHERE name=?` +- *numeric* - Numeric positional style, eg. `WHERE name=:1` +- *named* - Named style, eg. `WHERE name=:paramname` +- *format* - printf format codes, eg. `WHERE name=%s` +- *pyformat* - Python format codes, eg. `WHERE name=%(paramname)s` + + +#### pg8000.dbapi.STRING + +String type oid. + + +#### pg8000.dbapi.BINARY + + +#### pg8000.dbapi.NUMBER + +Numeric type oid. + + +#### pg8000.dbapi.DATETIME + +Timestamp type oid + + +#### pg8000.dbapi.ROWID + +ROWID type oid + + +### Functions + +#### pg8000.dbapi.connect(user, host='localhost', database=None, port=5432, password=None, source\_address=None, unix\_sock=None, ssl\_context=None, timeout=None, tcp\_keepalive=True, applicationa_name=None, replication=None, sock=None) + +Creates a connection to a PostgreSQL database. + +- *user* - The username to connect to the PostgreSQL server with. If your server character encoding is not `ascii` or `utf8`, then you need to provide `user` as bytes, eg. `'my_name'.encode('EUC-JP')`. +- *host* - The hostname of the PostgreSQL server to connect with. Providing this parameter is necessary for TCP/IP connections. One of either `host` or `unix_sock` must be provided. The default is `localhost`. +- *database* - The name of the database instance to connect with. If `None` then the PostgreSQL server will assume the database name is the same as the username. If your server character encoding is not `ascii` or `utf8`, then you need to provide `database` as bytes, eg. `'my_db'.encode('EUC-JP')`. +- *port* - The TCP/IP port of the PostgreSQL server instance. This parameter defaults to `5432`, the registered common port of PostgreSQL TCP/IP servers. +- *password* - The user password to connect to the server with. This parameter is optional; if omitted and the database server requests password-based authentication, the connection will fail to open. If this parameter is provided but not requested by the server, no error will occur. If your server character encoding is not `ascii` or `utf8`, then you need to provide `password` as bytes, eg. `'my_password'.encode('EUC-JP')`. +- *source_address* - The source IP address which initiates the connection to the PostgreSQL server. The default is `None` which means that the operating system will choose the source address. +- *unix_sock* - The path to the UNIX socket to access the database through, for example, `'/tmp/.s.PGSQL.5432'`. One of either `host` or `unix_sock` must be provided. +- *ssl_context* - This governs SSL encryption for TCP/IP sockets. It can have four values: + - `None`, the default, meaning that an attempt will be made to connect over SSL, but if this is rejected by the server then pg8000 will fall back to using a plain socket. + - `True`, means use SSL with an `ssl.SSLContext` with the minimum of checks. + - `False`, means to not attempt to create an SSL socket. + - An instance of `ssl.SSLContext` which will be used to create the SSL connection. +- *timeout* - This is the time in seconds before the connection to the server will time out. The default is `None` which means no timeout. +- *tcp_keepalive* - If `True` then use [TCP keepalive](https://en.wikipedia.org/wiki/Keepalive#TCP_keepalive). The default is `True`. +- *application_name* - Sets the [application\_name](https://www.postgresql.org/docs/current/runtime-config-logging.html#GUC-APPLICATION-NAME). If your server character encoding is not `ascii` or `utf8`, then you need to provide values as bytes, eg. `'my_application_name'.encode('EUC-JP')`. The default is `None` which means that the server will set the application name. +- *replication* - Used to run in [streaming replication mode](https://www.postgresql.org/docs/current/protocol-replication.html). If your server character encoding is not `ascii` or `utf8`, then you need to provide values as bytes, eg. `'database'.encode('EUC-JP')`. +- *sock* - A socket-like object to use for the connection. For example, `sock` could be a plain `socket.socket`, or it could represent an SSH tunnel or perhaps an `ssl.SSLSocket` to an SSL proxy. If an `ssl.SSLContext` is provided, then it will be used to attempt to create an SSL socket from the provided socket. + + +#### pg8000.dbapi.Date(year, month, day) + +Construct an object holding a date value. + +This property is part of the `DBAPI 2.0 specification +<http://www.python.org/dev/peps/pep-0249/>`_. + +Returns: `datetime.date` + + +#### pg8000.dbapi.Time(hour, minute, second) + +Construct an object holding a time value. + +Returns: `datetime.time` + + +#### pg8000.dbapi.Timestamp(year, month, day, hour, minute, second) + +Construct an object holding a timestamp value. + +Returns: `datetime.datetime` + + +#### pg8000.dbapi.DateFromTicks(ticks) + +Construct an object holding a date value from the given ticks value (number of seconds +since the epoch). + +Returns: `datetime.datetime` + + +#### pg8000.dbapi.TimeFromTicks(ticks) + +Construct an object holding a time value from the given ticks value (number of seconds +since the epoch). + +Returns: `datetime.time` + + +#### pg8000.dbapi.TimestampFromTicks(ticks) + +Construct an object holding a timestamp value from the given ticks value (number of +seconds since the epoch). + +Returns: `datetime.datetime` + +#### pg8000.dbapi.Binary(value) -Native API Docs ---------------- +Construct an object holding binary data. -`Native API Docs <docs/native_api_docs.rst>`_ +Returns: `bytes` -DB-API 2 Docs -------------- +### Generic Exceptions -`DB-API 2 Docs <docs/dbapi2_docs.rst>`_ +Pg8000 uses the standard DBAPI 2.0 exception tree as "generic" exceptions.

For example, if the interface attempts to use an SSL +connection but the server refuses, an InterfaceError will be raised. + + +#### pg8000.dbapi.DatabaseError + +Generic exception raised for errors that are related to the database. This exception is +currently never raised by pg8000. + + +#### pg8000.dbapi.DataError + +Generic exception raised for errors that are due to problems with the processed data. +This exception is not currently raised by pg8000. + + +#### pg8000.dbapi.OperationalError + +Generic exception raised for errors that are related to the database's operation and not +necessarily under the control of the programmer. This exception is currently never +raised by pg8000. + + +#### pg8000.dbapi.IntegrityError + +Generic exception raised when the relational integrity of the database is affected. This +exception is not currently raised by pg8000. + + +#### pg8000.dbapi.InternalError + +Generic exception raised when the database encounters an internal error. This is +currently only raised when unexpected state occurs in the pg8000 interface itself, and +is typically the result of a interface bug. + + +#### pg8000.dbapi.ProgrammingError + +Generic exception raised for programming errors. For example, this exception is raised +if more parameter fields are in a query string than there are available parameters. + + +#### pg8000.dbapi.NotSupportedError + +Generic exception raised in case a method or database API was used which is not +supported by the database. + + +### Classes + + +#### pg8000.dbapi.Connection + +A connection object is returned by the `pg8000.dbapi.connect()` function. It represents a +single physical connection to a PostgreSQL database. + + +#### pg8000.dbapi.Connection.autocommit + +Following the DB-API specification, autocommit is off by default. It can be turned on by +setting this boolean pg8000-specific autocommit property to ``True``. + + +#### pg8000.dbapi.Connection.close() + +Closes the database connection. + + +#### pg8000.dbapi.Connection.cursor() + +Creates a `pg8000.dbapi.Cursor` object bound to this connection. + + +#### pg8000.dbapi.Connection.rollback() + +Rolls back the current database transaction. + + +#### pg8000.dbapi.Connection.tpc_begin(xid) + +Begins a TPC transaction with the given transaction ID xid. This method should be +called outside of a transaction (i.e. nothing may have executed since the last +`commit()` or `rollback()`. Furthermore, it is an error to call `commit()` or +`rollback()` within the TPC transaction. A `ProgrammingError` is raised, if the +application calls `commit()` or `rollback()` during an active TPC transaction. + + +#### pg8000.dbapi.Connection.tpc_commit(xid=None) + +When called with no arguments, `tpc_commit()` commits a TPC transaction previously +prepared with `tpc_prepare()`. If `tpc_commit()` is called prior to +`tpc_prepare()`, a single phase commit is performed. A transaction manager may choose +to do this if only a single resource is participating in the global transaction. + +When called with a transaction ID `xid`, the database commits the given transaction. +If an invalid transaction ID is provided, a `ProgrammingError` will be raised. This +form should be called outside of a transaction, and is intended for use in recovery. + +On return, the TPC transaction is ended. + + +#### pg8000.dbapi.Connection.tpc_prepare() + +Performs the first phase of a transaction started with `.tpc_begin()`. A +`ProgrammingError` is be raised if this method is called outside of a TPC transaction. + +After calling `tpc_prepare()`, no statements can be executed until `tpc_commit()` or +`tpc_rollback()` have been called. + + +#### pg8000.dbapi.Connection.tpc_recover() + +Returns a list of pending transaction IDs suitable for use with `tpc_commit(xid)` or +`tpc_rollback(xid)`. + + +#### pg8000.dbapi.Connection.tpc_rollback(xid=None) + +When called with no arguments, `tpc_rollback()` rolls back a TPC transaction. It may +be called before or after `tpc_prepare()`. + +When called with a transaction ID xid, it rolls back the given transaction. If an +invalid transaction ID is provided, a `ProgrammingError` is raised. This form should +be called outside of a transaction, and is intended for use in recovery. + +On return, the TPC transaction is ended. + + +#### pg8000.dbapi.Connection.xid(format_id, global_transaction_id, branch_qualifier) + +Create a Transaction IDs (only global_transaction_id is used in pg) format_id and +branch_qualifier are not used in postgres global_transaction_id may be any string +identifier supported by postgres returns a tuple (format_id, global_transaction_id, +branch_qualifier) + + +#### pg8000.dbapi.Cursor + +A cursor object is returned by the `pg8000.dbapi.Connection.cursor()` method of a +connection. It has the following attributes and methods: + +##### pg8000.dbapi.Cursor.arraysize + +This read/write attribute specifies the number of rows to fetch at a time with +`pg8000.dbapi.Cursor.fetchmany()`. It defaults to 1. + + +##### pg8000.dbapi.Cursor.connection + +This read-only attribute contains a reference to the connection object (an instance of +`pg8000.dbapi.Connection`) on which the cursor was created. + + +##### pg8000.dbapi.Cursor.rowcount + +This read-only attribute contains the number of rows that the last `execute()` or +`executemany()` method produced (for query statements like `SELECT`) or affected +(for modification statements like `UPDATE`. + +The value is -1 if: + +- No `execute()` or `executemany()` method has been performed yet on the cursor. +- There was no rowcount associated with the last `execute()`. +- At least one of the statements executed as part of an `executemany()` had no row + count associated with it. + + +##### pg8000.dbapi.Cursor.description + +This read-only attribute is a sequence of 7-item sequences. Each value contains +information describing one result column. The 7 items returned for each column are +(name, type_code, display_size, internal_size, precision, scale, null_ok). Only the +first two values are provided by the current implementation. + + +##### pg8000.dbapi.Cursor.close() + +Closes the cursor. + + +##### pg8000.dbapi.Cursor.execute(operation, args=None, stream=None) + +Executes a database operation. Parameters may be provided as a sequence, or as a +mapping, depending upon the value of `pg8000.dbapi.paramstyle`. Returns the cursor, +which may be iterated over. + +- *operation* - The SQL statement to execute. +- *args* - If `pg8000.dbapi.paramstyle` is `qmark`, `numeric`, or `format`, this argument should be an array of parameters to bind into the statement. If `pg8000.dbapi.paramstyle` is `named`, the argument should be a `dict` mapping of parameters. If `pg8000.dbapi.paramstyle` is `pyformat`, the argument value may be either an array or a mapping. +- *stream* - This is a pg8000 extension for use with the PostgreSQL [COPY](http://www.postgresql.org/docs/current/static/sql-copy.html) command. For a `COPY FROM` the parameter must be a readable file-like object, and for `COPY TO` it must be writable. + + +##### pg8000.dbapi.Cursor.executemany(operation, param_sets) + +Prepare a database operation, and then execute it against all parameter sequences or +mappings provided. + +- *operation* - The SQL statement to execute. +- *parameter_sets* - A sequence of parameters to execute the statement with. The values in the sequence should be sequences or mappings of parameters, the same as the args argument of the `pg8000.dbapi.Cursor.execute()` method. + + +##### pg8000.dbapi.Cursor.callproc(procname, parameters=None) + +Call a stored database procedure with the given name and optional parameters. + +- *procname* - The name of the procedure to call. +- *parameters* - A list of parameters. + + +##### pg8000.dbapi.Cursor.fetchall() + +Fetches all remaining rows of a query result. + +Returns: A sequence, each entry of which is a sequence of field values making up a row. + + +##### pg8000.dbapi.Cursor.fetchmany(size=None) + +Fetches the next set of rows of a query result. + +- *size* - The number of rows to fetch when called. If not provided, the `pg8000.dbapi.Cursor.arraysize` attribute value is used instead. + +Returns: A sequence, each entry of which is a sequence of field values making up a row. +If no more rows are available, an empty sequence will be returned. + + +##### pg8000.dbapi.Cursor.fetchone() + +Fetch the next row of a query result set. + +Returns: A row as a sequence of field values, or `None` if no more rows are available. + + +##### pg8000.dbapi.Cursor.setinputsizes(\*sizes) + +Used to set the parameter types of the next query. This is useful if it's difficult for +pg8000 to work out the types from the parameters themselves (eg. for parameters of type +None). + +- *sizes* - Positional parameters that are either the Python type of the parameter to be sent, or the PostgreSQL oid. Common oids are available as constants such as `pg8000.STRING`, `pg8000.INTEGER`, `pg8000.TIME` etc. + + +##### pg8000.dbapi.Cursor.setoutputsize(size, column=None) + +Not implemented by pg8000. + + +#### pg8000.dbapi.Interval + +An Interval represents a measurement of time. In PostgreSQL, an interval is defined in +the measure of months, days, and microseconds; as such, the pg8000 interval type +represents the same information. + +Note that values of the `pg8000.dbapi.Interval.microseconds`, +`pg8000.dbapi.Interval.days`, and `pg8000.dbapi.Interval.months` properties are +independently measured and cannot be converted to each other. A month may be 28, 29, 30, +or 31 days, and a day may occasionally be lengthened slightly by a leap second. + + +## Design Decisions + +For the `Range` type, the constructor follows the [PostgreSQL range constructor functions +](https://www.postgresql.org/docs/current/rangetypes.html#RANGETYPES-CONSTRUCT) +which makes [[closed, open)](https://fhur.me/posts/always-use-closed-open-intervals) the easiest to express: +```python >>> from pg8000.types import Range >>> >>> pg_range = Range(2, 6) +``` -Tests ------ -- Install `tox <http://testrun.org/tox/latest/>`_: ``pip install tox`` +## Tests -- Enable the PostgreSQL hstore extension by running the SQL command: - ``create extension hstore;`` +- Install [tox](http://testrun.org/tox/latest/): `pip install tox` -- Add a line to ``pg_hba.conf`` for the various authentication options: +- Enable the PostgreSQL hstore extension by running the SQL command: + `create extension hstore;` -:: +- Add a line to `pg_hba.conf` for the various authentication options: - host pg8000_md5 all 127.0.0.1/32 md5 - host pg8000_gss all 127.0.0.1/32 gss - host pg8000_password all 127.0.0.1/32 password - host pg8000_scram_sha_256 all 127.0.0.1/32 scram-sha-256 - host all all 127.0.0.1/32 trust +``` +host pg8000_md5 all 127.0.0.1/32 md5 +host pg8000_gss all 127.0.0.1/32 gss +host pg8000_password all 127.0.0.1/32 password +host pg8000_scram_sha_256 all 127.0.0.1/32 scram-sha-256 +host all all 127.0.0.1/32 trust +``` -- Set password encryption to ``scram-sha-256`` in ``postgresql.conf``: - ``password_encryption = 'scram-sha-256'`` +- Set password encryption to `scram-sha-256` in `postgresql.conf`: + `password_encryption = 'scram-sha-256'` -- Set the password for the postgres user: ``ALTER USER postgresql WITH PASSWORD 'pw';`` +- Set the password for the postgres user: `ALTER USER postgresql WITH PASSWORD 'pw';` -- Run ``tox`` from the ``pg8000`` directory: ``tox`` +- Run `tox` from the `pg8000` directory: `tox` This will run the tests against the Python version of the virtual environment, on the -machine, and the installed PostgreSQL version listening on port 5432, or the ``PGPORT`` +machine, and the installed PostgreSQL version listening on port 5432, or the `PGPORT` environment variable if set. -Benchmarks are run as part of the test suite at ``tests/test_benchmarks.py``. +Benchmarks are run as part of the test suite at `tests/test_benchmarks.py`. + + +## Doing A Release Of pg8000 + +Run `tox` to make sure all tests pass, then update the release notes, then do: + + +``` +git tag -a x.y.z -m "version x.y.z" +rm -r dist +python -m build +twine upload dist/* +``` + + +## Release Notes + +### Version 1.31.1, 2024-04-01 + +- Move to src style layout, and also for packaging use Hatch rather than setuptools.

There are many SQL statements that one might think would have parameters, +but don't. For these cases the SQL has to be created manually, being careful to use the +`identifier()` and `literal()` functions to escape the values to avoid [SQL injection +attacks](https://en.wikipedia.org/wiki/SQL_injection>): + +```python +>>> from pg8000.native import Connection, identifier, literal +>>> +>>> con = Connection("postgres", password="cpsnow") +>>> +>>> channel = 'top_secret' +>>> payload = 'Aliens Landed!' +>>> con.run(f"LISTEN {identifier(channel)}") +>>> con.run(f"NOTIFY {identifier(channel)}, {literal(payload)}") +>>> +>>> con.notifications[0] +(..., 'top_secret', 'Aliens Landed!') +>>> +>>> con.close() + +``` + + +### COPY FROM And TO A Stream + +The SQL [COPY](https://www.postgresql.org/docs/current/sql-copy.html) statement can be +used to copy from and to a file or file-like object.

Since it's case sensitive and contains a space, +you'd have to [surround it by double quotes +](https://www.postgresql.org/docs/current/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIER). +But you can't do: + +```python +>>> import pg8000.native +>>> +>>> con = pg8000.native.Connection("postgres", password="cpsnow") +>>> +>>> con.run("select 'hello' as "My Column"") +Traceback (most recent call last): +SyntaxError: invalid syntax... +>>> +>>> con.close() + +``` + +since Python uses double quotes to delimit string literals, so one solution is +to use Python's [triple quotes +](https://docs.python.org/3/tutorial/introduction.html#strings) to delimit the string +instead: + +```python +>>> import pg8000.native +>>> +>>> con = pg8000.native.Connection("postgres", password="cpsnow") +>>> +>>> con.run('''SELECT 'hello' AS "My Column"''') +[['hello']] +>>> +>>> con.close() + +``` + +another solution, that's especially useful if the identifier comes from an untrusted +source, is to use the `identifier()` function, which correctly quotes and escapes the +identifier as needed: + +```python +>>> from pg8000.native import Connection, identifier +>>> +>>> con = Connection("postgres", password="cpsnow") +>>> +>>> sql = f"SELECT 'hello' as {identifier('My Column')}" +>>> print(sql) +SELECT 'hello' as "My Column" +>>> +>>> con.run(sql) +[['hello']] +>>> +>>> con.close() + +``` + +this approach guards against [SQL injection attacks +](https://en.wikipedia.org/wiki/SQL_injection). One thing to note if you're using +explicit schemas (eg. `pg_catalog.pg_language`) is that the schema name and table name +are both separate identifiers. So to escape them you'd do: + +```python +>>> from pg8000.native import Connection, identifier +>>> +>>> con = Connection("postgres", password="cpsnow") +>>> +>>> query = ( +... f"SELECT lanname FROM {identifier('pg_catalog')}.{identifier('pg_language')} " +... f"WHERE lanname = 'sql'" +... ) +>>> print(query) +SELECT lanname FROM pg_catalog.pg_language WHERE lanname = 'sql' +>>> +>>> con.run(query) +[['sql']] +>>> +>>> con.close() + +``` + + +### Custom adapter from a Python type to a PostgreSQL type + +pg8000 has a mapping from Python types to PostgreSQL types for when it needs to send +SQL parameters to the server. The default mapping that comes with pg8000 is designed to +work well in most cases, but you might want to add or replace the default mapping. + +A Python `datetime.timedelta` object is sent to the server as a PostgreSQL +`interval` type, which has the `oid` 1186. But let's say we wanted to create our +own Python class to be sent as an `interval` type.

See below for an example of how to change the +mapping from PostgreSQL to Python. + + +### Custom adapter from a PostgreSQL type to a Python type + +pg8000 has a mapping from PostgreSQL types to Python types for when it receives SQL +results from the server. The default mapping that comes with pg8000 is designed to work +well in most cases, but you might want to add or replace the default mapping. + +If pg8000 receives PostgreSQL `interval` type, which has the `oid` 1186, it converts +it into a Python `datetime.timedelta` object.

'postgres', password="cpsnow", ssl_context=ssl_context) +>>> con.run("SELECT 'Work is the curse of the drinking classes.'") +[['Work is the curse of the drinking classes.']] +>>> con.close() + +``` + +It may be that your PostgreSQL server is behind an SSL proxy server in which case you +can give pg8000 the SSL socket with the `sock` parameter, and then set +`ssl_context=False` which means that no attempt will be made to create an SSL connection +to the server. + + +### Server-Side Cursors + +You can use the SQL commands [DECLARE +](https://www.postgresql.org/docs/current/sql-declare.html), +[FETCH](https://www.postgresql.org/docs/current/sql-fetch.html), +[MOVE](https://www.postgresql.org/docs/current/sql-move.html) and +[CLOSE](https://www.postgresql.org/docs/current/sql-close.html) to manipulate +server-side cursors.

If a query has no +parameters, pg8000 uses the 'simple query protocol'. If a query does have parameters, +pg8000 uses the 'extended query protocol' with unnamed prepared statements. The steps +for a query with parameters are: + +1. Query comes in. + +2. Send a PARSE message to the server to create an unnamed prepared statement. + +3. Send a BIND message to run against the unnamed prepared statement, resulting in an + unnamed portal on the server. + +4. Send an EXECUTE message to read all the results from the portal. + +It's also possible to use named prepared statements. In which case the prepared +statement persists on the server, and represented in pg8000 using a +`PreparedStatement` object. This means that the PARSE step gets executed once up +front, and then only the BIND and EXECUTE steps are repeated subsequently. + +There are a lot of PostgreSQL data types, but few primitive data types in Python. By +default, pg8000 doesn't send PostgreSQL data type information in the PARSE step, in +which case PostgreSQL assumes the types implied by the SQL statement. In some cases +PostgreSQL can't work out a parameter type and so an [explicit cast +](https://www.postgresql.org/docs/current/static/sql-expressions.html#SQL-SYNTAX-TYPE-CASTS) +can be used in the SQL. + +In the FEBE protocol, each query parameter can be sent to the server either as binary +or text according to the format code. In pg8000 the parameters are always sent as text. + +Occasionally, the network connection between pg8000 and the server may go down. If +pg8000 encounters a network problem it'll raise an `InterfaceError` with the message +`network error` and with the original exception set as the [cause +](https://docs.python.org/3/reference/simple_stmts.html#the-raise-statement). + + +## Native API Docs + +### pg8000.native.Error + +Generic exception that is the base exception of the other error exceptions. + + +### pg8000.native.InterfaceError + +For errors that originate within pg8000. + + +### pg8000.native.DatabaseError + +For errors that originate from the server. + +### pg8000.native.Connection(user, host='localhost', database=None, port=5432, password=None, source\_address=None, unix\_sock=None, ssl\_context=None, timeout=None, tcp\_keepalive=True, application\_name=None, replication=None, sock=None) + +Creates a connection to a PostgreSQL database. + +- *user* - The username to connect to the PostgreSQL server with. If your server character encoding is not `ascii` or `utf8`, then you need to provide `user` as bytes, eg. `'my_name'.encode('EUC-JP')`. +- *host* - The hostname of the PostgreSQL server to connect with. Providing this parameter is necessary for TCP/IP connections. One of either `host` or `unix_sock` must be provided. The default is `localhost`. +- *database* - The name of the database instance to connect with. If `None` then the PostgreSQL server will assume the database name is the same as the username. If your server character encoding is not `ascii` or `utf8`, then you need to provide `database` as bytes, eg. `'my_db'.encode('EUC-JP')`. +- *port* - The TCP/IP port of the PostgreSQL server instance. This parameter defaults to `5432`, the registered common port of PostgreSQL TCP/IP servers. +- *password* - The user password to connect to the server with. This parameter is optional; if omitted and the database server requests password-based authentication, the connection will fail to open. If this parameter is provided but not requested by the server, no error will occur. If your server character encoding is not `ascii` or `utf8`, then you need to provide `password` as bytes, eg. `'my_password'.encode('EUC-JP')`. +- *source_address* - The source IP address which initiates the connection to the PostgreSQL server. The default is `None` which means that the operating system will choose the source address. +- *unix_sock* - The path to the UNIX socket to access the database through, for example, `'/tmp/.s.PGSQL.5432'`. One of either `host` or `unix_sock` must be provided. +- *ssl_context* - This governs SSL encryption for TCP/IP sockets. It can have four values: + - `None`, the default, meaning that an attempt will be made to connect over SSL, but if this is rejected by the server then pg8000 will fall back to using a plain socket. + - `True`, means use SSL with an `ssl.SSLContext` with the minimum of checks. + - `False`, means to not attempt to create an SSL socket. + - An instance of `ssl.SSLContext` which will be used to create the SSL connection. +- *timeout* - This is the time in seconds before the connection to the server will time out. The default is `None` which means no timeout. +- *tcp_keepalive* - If `True` then use [TCP keepalive](https://en.wikipedia.org/wiki/Keepalive#TCP_keepalive). The default is `True`. +- *application_name* - Sets the [application\_name](https://www.postgresql.org/docs/current/runtime-config-logging.html#GUC-APPLICATION-NAME). If your server character encoding is not `ascii` or `utf8`, then you need to provide values as bytes, eg. `'my_application_name'.encode('EUC-JP')`. The default is `None` which means that the server will set the application name. +- *replication* - Used to run in [streaming replication mode](https://www.postgresql.org/docs/current/protocol-replication.html). If your server character encoding is not `ascii` or `utf8`, then you need to provide values as bytes, eg. `'database'.encode('EUC-JP')`. +- *sock* - A socket-like object to use for the connection. For example, `sock` could be a plain `socket.socket`, or it could represent an SSH tunnel or perhaps an `ssl.SSLSocket` to an SSL proxy. If an `ssl.SSLContext` is provided, then it will be used to attempt to create an SSL socket from the provided socket. + +### pg8000.native.Connection.notifications + +A deque of server-side +[notifications](https://www.postgresql.org/docs/current/sql-notify.html) received by +this database connection (via the `LISTEN` / `NOTIFY` PostgreSQL commands).

This value defaults to "format", in which parameters are +marked in this format: "WHERE name=%s". + +As an extension to the DBAPI specification, this value is not constant; it can be +changed to any of the following values: + +- *qmark* - Question mark style, eg. `WHERE name=?` +- *numeric* - Numeric positional style, eg. `WHERE name=:1` +- *named* - Named style, eg. `WHERE name=:paramname` +- *format* - printf format codes, eg. `WHERE name=%s` +- *pyformat* - Python format codes, eg. `WHERE name=%(paramname)s` + + +#### pg8000.dbapi.STRING + +String type oid. + + +#### pg8000.dbapi.BINARY + + +#### pg8000.dbapi.NUMBER + +Numeric type oid. + + +#### pg8000.dbapi.DATETIME + +Timestamp type oid + + +#### pg8000.dbapi.ROWID + +ROWID type oid + + +### Functions + +#### pg8000.dbapi.connect(user, host='localhost', database=None, port=5432, password=None, source\_address=None, unix\_sock=None, ssl\_context=None, timeout=None, tcp\_keepalive=True, applicationa_name=None, replication=None, sock=None) + +Creates a connection to a PostgreSQL database. + +- *user* - The username to connect to the PostgreSQL server with. If your server character encoding is not `ascii` or `utf8`, then you need to provide `user` as bytes, eg. `'my_name'.encode('EUC-JP')`. +- *host* - The hostname of the PostgreSQL server to connect with. Providing this parameter is necessary for TCP/IP connections. One of either `host` or `unix_sock` must be provided. The default is `localhost`. +- *database* - The name of the database instance to connect with. If `None` then the PostgreSQL server will assume the database name is the same as the username. If your server character encoding is not `ascii` or `utf8`, then you need to provide `database` as bytes, eg. `'my_db'.encode('EUC-JP')`. +- *port* - The TCP/IP port of the PostgreSQL server instance. This parameter defaults to `5432`, the registered common port of PostgreSQL TCP/IP servers. +- *password* - The user password to connect to the server with. This parameter is optional; if omitted and the database server requests password-based authentication, the connection will fail to open. If this parameter is provided but not requested by the server, no error will occur. If your server character encoding is not `ascii` or `utf8`, then you need to provide `password` as bytes, eg. `'my_password'.encode('EUC-JP')`. +- *source_address* - The source IP address which initiates the connection to the PostgreSQL server. The default is `None` which means that the operating system will choose the source address. +- *unix_sock* - The path to the UNIX socket to access the database through, for example, `'/tmp/.s.PGSQL.5432'`. One of either `host` or `unix_sock` must be provided. +- *ssl_context* - This governs SSL encryption for TCP/IP sockets. It can have four values: + - `None`, the default, meaning that an attempt will be made to connect over SSL, but if this is rejected by the server then pg8000 will fall back to using a plain socket. + - `True`, means use SSL with an `ssl.SSLContext` with the minimum of checks. + - `False`, means to not attempt to create an SSL socket. + - An instance of `ssl.SSLContext` which will be used to create the SSL connection. +- *timeout* - This is the time in seconds before the connection to the server will time out. The default is `None` which means no timeout. +- *tcp_keepalive* - If `True` then use [TCP keepalive](https://en.wikipedia.org/wiki/Keepalive#TCP_keepalive). The default is `True`. +- *application_name* - Sets the [application\_name](https://www.postgresql.org/docs/current/runtime-config-logging.html#GUC-APPLICATION-NAME). If your server character encoding is not `ascii` or `utf8`, then you need to provide values as bytes, eg. `'my_application_name'.encode('EUC-JP')`. The default is `None` which means that the server will set the application name. +- *replication* - Used to run in [streaming replication mode](https://www.postgresql.org/docs/current/protocol-replication.html). If your server character encoding is not `ascii` or `utf8`, then you need to provide values as bytes, eg. `'database'.encode('EUC-JP')`. +- *sock* - A socket-like object to use for the connection. For example, `sock` could be a plain `socket.socket`, or it could represent an SSH tunnel or perhaps an `ssl.SSLSocket` to an SSL proxy. If an `ssl.SSLContext` is provided, then it will be used to attempt to create an SSL socket from the provided socket. + + +#### pg8000.dbapi.Date(year, month, day) + +Construct an object holding a date value. + +This property is part of the `DBAPI 2.0 specification +<http://www.python.org/dev/peps/pep-0249/>`_. + +Returns: `datetime.date` + + +#### pg8000.dbapi.Time(hour, minute, second) + +Construct an object holding a time value. + +Returns: `datetime.time` + + +#### pg8000.dbapi.Timestamp(year, month, day, hour, minute, second) + +Construct an object holding a timestamp value. + +Returns: `datetime.datetime` + + +#### pg8000.dbapi.DateFromTicks(ticks) + +Construct an object holding a date value from the given ticks value (number of seconds +since the epoch). + +Returns: `datetime.datetime` + + +#### pg8000.dbapi.TimeFromTicks(ticks) + +Construct an object holding a time value from the given ticks value (number of seconds +since the epoch). + +Returns: `datetime.time` + + +#### pg8000.dbapi.TimestampFromTicks(ticks) + +Construct an object holding a timestamp value from the given ticks value (number of +seconds since the epoch). + +Returns: `datetime.datetime` + + +#### pg8000.dbapi.Binary(value) + +Construct an object holding binary data. + +Returns: `bytes` + + +### Generic Exceptions + +Pg8000 uses the standard DBAPI 2.0 exception tree as "generic" exceptions. Generally, +more specific exception types are raised; these specific exception types are derived +from the generic exceptions. + +#### pg8000.dbapi.Warning + +Generic exception raised for important database warnings like data truncations. This +exception is not currently used by pg8000. + + +#### pg8000.dbapi.Error + +Generic exception that is the base exception of all other error exceptions. + + +#### pg8000.dbapi.InterfaceError + +Generic exception raised for errors that are related to the database interface rather +than the database itself. For example, if the interface attempts to use an SSL +connection but the server refuses, an InterfaceError will be raised. + + +#### pg8000.dbapi.DatabaseError + +Generic exception raised for errors that are related to the database. This exception is +currently never raised by pg8000. + + +#### pg8000.dbapi.DataError + +Generic exception raised for errors that are due to problems with the processed data. +This exception is not currently raised by pg8000. + + +#### pg8000.dbapi.OperationalError + +Generic exception raised for errors that are related to the database's operation and not +necessarily under the control of the programmer. This exception is currently never +raised by pg8000. + + +#### pg8000.dbapi.IntegrityError + +Generic exception raised when the relational integrity of the database is affected. This +exception is not currently raised by pg8000. + + +#### pg8000.dbapi.InternalError + +Generic exception raised when the database encounters an internal error. This is +currently only raised when unexpected state occurs in the pg8000 interface itself, and +is typically the result of a interface bug. + + +#### pg8000.dbapi.ProgrammingError + +Generic exception raised for programming errors. For example, this exception is raised +if more parameter fields are in a query string than there are available parameters. + + +#### pg8000.dbapi.NotSupportedError + +Generic exception raised in case a method or database API was used which is not +supported by the database. + + +### Classes + + +#### pg8000.dbapi.Connection + +A connection object is returned by the `pg8000.dbapi.connect()` function. It represents a +single physical connection to a PostgreSQL database. + + +#### pg8000.dbapi.Connection.autocommit + +Following the DB-API specification, autocommit is off by default. It can be turned on by +setting this boolean pg8000-specific autocommit property to ``True``. + + +#### pg8000.dbapi.Connection.close() + +Closes the database connection. + + +#### pg8000.dbapi.Connection.cursor() + +Creates a `pg8000.dbapi.Cursor` object bound to this connection. + + +#### pg8000.dbapi.Connection.rollback() + +Rolls back the current database transaction. + + +#### pg8000.dbapi.Connection.tpc_begin(xid) + +Begins a TPC transaction with the given transaction ID xid. This method should be +called outside of a transaction (i.e. nothing may have executed since the last +`commit()` or `rollback()`. Furthermore, it is an error to call `commit()` or +`rollback()` within the TPC transaction. A `ProgrammingError` is raised, if the +application calls `commit()` or `rollback()` during an active TPC transaction. + + +#### pg8000.dbapi.Connection.tpc_commit(xid=None) + +When called with no arguments, `tpc_commit()` commits a TPC transaction previously +prepared with `tpc_prepare()`. If `tpc_commit()` is called prior to +`tpc_prepare()`, a single phase commit is performed. A transaction manager may choose +to do this if only a single resource is participating in the global transaction. + +When called with a transaction ID `xid`, the database commits the given transaction. +If an invalid transaction ID is provided, a `ProgrammingError` will be raised. This +form should be called outside of a transaction, and is intended for use in recovery. + +On return, the TPC transaction is ended. + + +#### pg8000.dbapi.Connection.tpc_prepare() + +Performs the first phase of a transaction started with `.tpc_begin()`. A +`ProgrammingError` is be raised if this method is called outside of a TPC transaction. + +After calling `tpc_prepare()`, no statements can be executed until `tpc_commit()` or +`tpc_rollback()` have been called. + + +#### pg8000.dbapi.Connection.tpc_recover() + +Returns a list of pending transaction IDs suitable for use with `tpc_commit(xid)` or +`tpc_rollback(xid)`. + + +#### pg8000.dbapi.Connection.tpc_rollback(xid=None) + +When called with no arguments, `tpc_rollback()` rolls back a TPC transaction. It may +be called before or after `tpc_prepare()`. + +When called with a transaction ID xid, it rolls back the given transaction. If an +invalid transaction ID is provided, a `ProgrammingError` is raised. This form should +be called outside of a transaction, and is intended for use in recovery. + +On return, the TPC transaction is ended. + + +#### pg8000.dbapi.Connection.xid(format_id, global_transaction_id, branch_qualifier) + +Create a Transaction IDs (only global_transaction_id is used in pg) format_id and +branch_qualifier are not used in postgres global_transaction_id may be any string +identifier supported by postgres returns a tuple (format_id, global_transaction_id, +branch_qualifier) + + +#### pg8000.dbapi.Cursor + +A cursor object is returned by the `pg8000.dbapi.Connection.cursor()` method of a +connection. It has the following attributes and methods: + +##### pg8000.dbapi.Cursor.arraysize + +This read/write attribute specifies the number of rows to fetch at a time with +`pg8000.dbapi.Cursor.fetchmany()`. It defaults to 1. + + +##### pg8000.dbapi.Cursor.connection + +This read-only attribute contains a reference to the connection object (an instance of +`pg8000.dbapi.Connection`) on which the cursor was created. + + +##### pg8000.dbapi.Cursor.rowcount + +This read-only attribute contains the number of rows that the last `execute()` or +`executemany()` method produced (for query statements like `SELECT`) or affected +(for modification statements like `UPDATE`. + +The value is -1 if: + +- No `execute()` or `executemany()` method has been performed yet on the cursor. +- There was no rowcount associated with the last `execute()`. +- At least one of the statements executed as part of an `executemany()` had no row + count associated with it. + + +##### pg8000.dbapi.Cursor.description + +This read-only attribute is a sequence of 7-item sequences. Each value contains +information describing one result column. The 7 items returned for each column are +(name, type_code, display_size, internal_size, precision, scale, null_ok). Only the +first two values are provided by the current implementation. + + +##### pg8000.dbapi.Cursor.close() + +Closes the cursor. + + +##### pg8000.dbapi.Cursor.execute(operation, args=None, stream=None) + +Executes a database operation. Parameters may be provided as a sequence, or as a +mapping, depending upon the value of `pg8000.dbapi.paramstyle`. Returns the cursor, +which may be iterated over. + +- *operation* - The SQL statement to execute. +- *args* - If `pg8000.dbapi.paramstyle` is `qmark`, `numeric`, or `format`, this argument should be an array of parameters to bind into the statement. If `pg8000.dbapi.paramstyle` is `named`, the argument should be a `dict` mapping of parameters. If `pg8000.dbapi.paramstyle` is `pyformat`, the argument value may be either an array or a mapping. +- *stream* - This is a pg8000 extension for use with the PostgreSQL [COPY](http://www.postgresql.org/docs/current/static/sql-copy.html) command. For a `COPY FROM` the parameter must be a readable file-like object, and for `COPY TO` it must be writable. + + +##### pg8000.dbapi.Cursor.executemany(operation, param_sets) + +Prepare a database operation, and then execute it against all parameter sequences or +mappings provided. + +- *operation* - The SQL statement to execute. +- *parameter_sets* - A sequence of parameters to execute the statement with. The values in the sequence should be sequences or mappings of parameters, the same as the args argument of the `pg8000.dbapi.Cursor.execute()` method. + + +##### pg8000.dbapi.Cursor.callproc(procname, parameters=None) + +Call a stored database procedure with the given name and optional parameters. + +- *procname* - The name of the procedure to call. +- *parameters* - A list of parameters. + + +##### pg8000.dbapi.Cursor.fetchall() + +Fetches all remaining rows of a query result. + +Returns: A sequence, each entry of which is a sequence of field values making up a row. + + +##### pg8000.dbapi.Cursor.fetchmany(size=None) + +Fetches the next set of rows of a query result. + +- *size* - The number of rows to fetch when called. If not provided, the `pg8000.dbapi.Cursor.arraysize` attribute value is used instead. + +Returns: A sequence, each entry of which is a sequence of field values making up a row. +If no more rows are available, an empty sequence will be returned. + + +##### pg8000.dbapi.Cursor.fetchone() + +Fetch the next row of a query result set. + +Returns: A row as a sequence of field values, or `None` if no more rows are available. + + +##### pg8000.dbapi.Cursor.setinputsizes(\*sizes) + +Used to set the parameter types of the next query. This is useful if it's difficult for +pg8000 to work out the types from the parameters themselves (eg. for parameters of type +None). + +- *sizes* - Positional parameters that are either the Python type of the parameter to be sent, or the PostgreSQL oid. Common oids are available as constants such as `pg8000.STRING`, `pg8000.INTEGER`, `pg8000.TIME` etc. + + +##### pg8000.dbapi.Cursor.setoutputsize(size, column=None) + +Not implemented by pg8000. + + +#### pg8000.dbapi.Interval + +An Interval represents a measurement of time. In PostgreSQL, an interval is defined in +the measure of months, days, and microseconds; as such, the pg8000 interval type +represents the same information. + +Note that values of the `pg8000.dbapi.Interval.microseconds`, +`pg8000.dbapi.Interval.days`, and `pg8000.dbapi.Interval.months` properties are +independently measured and cannot be converted to each other. A month may be 28, 29, 30, +or 31 days, and a day may occasionally be lengthened slightly by a leap second. + + +## Design Decisions + +For the `Range` type, the constructor follows the [PostgreSQL range constructor functions +](https://www.postgresql.org/docs/current/rangetypes.html#RANGETYPES-CONSTRUCT) +which makes [[closed, open)](https://fhur.me/posts/always-use-closed-open-intervals) +the easiest to express: + +```python +>>> from pg8000.types import Range +>>> +>>> pg_range = Range(2, 6) + +``` + + +## Tests + +- Install [tox](http://testrun.org/tox/latest/): `pip install tox` + +- Enable the PostgreSQL hstore extension by running the SQL command: + `create extension hstore;` + +- Add a line to `pg_hba.conf` for the various authentication options: + +``` +host pg8000_md5 all 127.0.0.1/32 md5 +host pg8000_gss all 127.0.0.1/32 gss +host pg8000_password all 127.0.0.1/32 password +host pg8000_scram_sha_256 all 127.0.0.1/32 scram-sha-256 +host all all 127.0.0.1/32 trust +``` + +- Set password encryption to `scram-sha-256` in `postgresql.conf`: + `password_encryption = 'scram-sha-256'` + +- Set the password for the postgres user: `ALTER USER postgresql WITH PASSWORD 'pw';` + +- Run `tox` from the `pg8000` directory: `tox` + +This will run the tests against the Python version of the virtual environment, on the +machine, and the installed PostgreSQL version listening on port 5432, or the `PGPORT` +environment variable if set. + +Benchmarks are run as part of the test suite at `tests/test_benchmarks.py`. + + +## Doing A Release Of pg8000 + +Run `tox` to make sure all tests pass, then update the release notes, then do: + + +``` +git tag -a x.y.z -m "version x.y.z" +rm -r dist +python -m build +twine upload dist/* +``` + + +## Release Notes + +### Version 1.31.1, 2024-04-01 + +- Move to src style layout, and also for packaging use Hatch rather than setuptools. This means that if the source distribution has a directory added to it (as is needed for packaging for OS distributions) the package can still be built. + + +### Version 1.31.0, 2024-03-31 + +- Now the `ssl_context` connection parameter can have one of four values: + - None - The default, meaning it'll try and connect over SSL but fall back to a plain socket if not. + - True - Will try and connect over SSL and fail if not. + - False - It'll not try to connect over SSL. + - SSLContext object - It'll use this object to connect over SSL. + + +### Version 1.30.5, 2024-02-22 + +- Fix bug that now means the number of parameters cam be as high as an unsigned 16 bit + integer will go. + + +### Version 1.30.4, 2024-01-03 + +- Add support for more range and multirange types. +- Make the `Connection.parameter_statuses` property a `dict` rather than a `dequeue`. + + +### Version 1.30.3, 2023-10-31 + +- Fix problem with PG date overflowing Python types. Now we return the `str` we got from the + server if we can't parse it. + + +### Version 1.30.2, 2023-09-17 + +- Bug fix where dollar-quoted string constants weren't supported. + + +### Version 1.30.1, 2023-07-29 + +- There was a problem uploading the previous version (1.30.0) to PyPI because the markup of the README.rst was invalid. There's now a step in the automated tests to check for this. + + +### Version 1.30.0, 2023-07-27 + +- Remove support for Python 3.7 +- Add a `sock` keyword parameter for creating a connection from a pre-configured socket. + + +### Version 1.29.8, 2023-06-16 + +- Ranges don't work with legacy API. + + +### Version 1.29.7, 2023-06-16 + +- Add support for PostgreSQL `range` and `multirange` types. Previously pg8000 would just return them as strings, but now they're returned as `Range` and lists of `Range`. +- The PostgreSQL `record` type is now returned as a `tuple` of strings, whereas before it was returned as one string. + + +### Version 1.29.6, 2023-05-29 + +- Fixed two bugs with composite types. Nulls should be represented by an empty string, and in an array of composite types, the elements should be surrounded by double quotes. + + +### Version 1.29.5, 2023-05-09 + +- Fixed bug where pg8000 didn't handle the case when the number of bytes received from a socket was fewer than requested. This was being interpreted as a network error, but in fact we just needed to wait until more bytes were available. +- When using the `PGInterval` type, if a response from the server contained the period `millennium`, it wasn't recognised. This was caused by a spelling mistake where we had `millenium` rather than `millennium`. +- Added support for sending PostgreSQL composite types. If a value is sent as a `tuple`, pg8000 will send it to the server as a `(` delimited composite string. + + +### Version 1.29.4, 2022-12-14 + +- Fixed bug in `pg8000.dbapi` in the `setinputsizes()` method where if a `size` was a recognized Python type, the method failed. + + +### Version 1.29.3, 2022-10-26 + +- Upgrade the SCRAM library to version 1.4.3. This adds support for the case where the client supports channel binding but the server doesn't. + + +### Version 1.29.2, 2022-10-09 + +- Fixed a bug where in a literal array, items such as `\n` and `\r` weren't escaped properly before being sent to the server. +- Fixed a bug where if the PostgreSQL server has a half-hour time zone set, values of type `timestamp with time zone` failed. This has been fixed by using the `parse` function of the `dateutil` package if the `datetime` parser fails. + + +### Version 1.29.1, 2022-05-23 + +- In trying to determine if there's been a failed commit, check for `ROLLBACK TO SAVEPOINT`. + + +### Version 1.29.0, 2022-05-21 + +- Implement a workaround for the [silent failed commit](https://github.com/tlocke/pg8000/issues/36) bug. +- Previously if an empty string was sent as the query an exception would be raised, but that isn't done now. + + +### Version 1.28.3, 2022-05-18 + +- Put back `__version__` attributes that were inadvertently removed. + + +### Version 1.28.2, 2022-05-17 + +- Use a build system that's compliant with PEP517. + + +### Version 1.28.1, 2022-05-17 + +- If when doing a `COPY FROM` the `stream` parameter is an iterator of `str`, pg8000 used to silently append a newline to the end. That no longer happens. + + +### Version 1.28.0, 2022-05-17 + +- When using the `COPY FROM` SQL statement, allow the `stream` parameter to be an iterable. + + +### Version 1.27.1, 2022-05-16 + +- The `seconds` attribute of `PGInterval` is now always a `float`, to cope with fractional seconds. +- Updated the `interval` parsers for `iso_8601` and `sql_standard` to take account of fractional seconds. + + +### Version 1.27.0, 2022-05-16 + +- It used to be that by default, if pg8000 received an `interval` type from the server and it was too big to fit into a `datetime.timedelta` then an exception would be raised. Now if an interval is too big for `datetime.timedelta` a `PGInterval` is returned. +- pg8000 now supports all the output formats for an `interval` (`postgres`, `postgres_verbose`, `iso_8601` and `sql_standard`). + + +### Version 1.26.1, 2022-04-23 + +- Make sure all tests are run by the GitHub Actions tests on commit. +- Remove support for Python 3.6 +- Remove support for PostgreSQL 9.6 + + +### Version 1.26.0, 2022-04-18 + +- When connecting, raise an `InterfaceError('network error')` rather than let the underlying `struct.error` float up. +- Make licence text the same as that used by the OSI. Previously the licence wording differed slightly from the BSD 3 Clause licence at https://opensource.org/licenses/BSD-3-Clause. This meant that automated tools didn't pick it up as being Open Source. The changes are believed to not alter the meaning of the license at all. + + +### Version 1.25.0, 2022-04-17 + +- Fix more cases where a `ResourceWarning` would be raise because of a socket that had been left open. +- We now have a single `InterfaceError` with the message 'network error' for all network errors, with the underlying exception held in the `cause` of the exception. + + +### Version 1.24.2, 2022-04-15 + +- To prevent a `ResourceWarning` close socket if a connection can't be created. + + +### Version 1.24.1, 2022-03-02 + +- Return pg +/-infinity dates as `str`. Previously +/-infinity pg values would cause an error when returned, but now we return +/-infinity as strings. + + +### Version 1.24.0, 2022-02-06 + +- Add SQL escape functions identifier() and literal() to the native API. For use when a query can't be parameterised and the SQL string has to be created using untrusted values. + + +### Version 1.23.0, 2021-11-13 + +- If a query has no parameters, then the query will no longer be parsed. Although there are performance benefits for doing this, the main reason is to avoid query rewriting, which can introduce errors. + + +### Version 1.22.1, 2021-11-10 + +- Fix bug in PGInterval type where `str()` failed for a millennia value. + + +### Version 1.22.0, 2021-10-13 + +- Rather than specifying the oids in the `Parse` step of the Postgres protocol, pg8000 now omits them, and so Postgres will use the oids it determines from the query. This makes the pg8000 code simpler and also it should also make the nuances of type matching more straightforward. diff --git a/contrib/python/pg8000/README.rst b/contrib/python/pg8000/README.rst deleted file mode 100644 index 55c26ddef3..0000000000 --- a/contrib/python/pg8000/README.rst +++ /dev/null @@ -1,1407 +0,0 @@ -====== -pg8000 -====== - -.. |ssl.SSLContext| replace:: ``ssl.SSLContext`` -.. _ssl.SSLContext: https://docs.python.org/3/library/ssl.html#ssl.SSLContext - -.. |ssl.create_default_context()| replace:: ``ssl.create_default_context()`` -.. _ssl.create_default_context(): https://docs.python.org/3/library/ssl.html#ssl.create_default_context - -pg8000 is a pure-`Python <https://www.python.org/>`_ -`PostgreSQL <http://www.postgresql.org/>`_ driver that complies with -`DB-API 2.0 <http://www.python.org/dev/peps/pep-0249/>`_.

The steps -for a query with parameters are: - -1. Query comes in. - -#. Send a PARSE message to the server to create an unnamed prepared statement. - -#. Send a BIND message to run against the unnamed prepared statement, resulting in an - unnamed portal on the server. - -#. Send an EXECUTE message to read all the results from the portal. - -It's also possible to use named prepared statements.
