/** Helps detect version mismatches between libpqxx headers and the libpqxx
* library binary.
*
* Sometimes users run into trouble linking their code against libpqxx because
* they build their own libpqxx, but the system also has a different version
* installed. The declarations in the headers against which they compile their
* code will differ from the ones used to build the libpqxx version they're
* using, leading to confusing link errors. The solution is to generate a link
* error when the libpqxx binary is not the same version as the libpqxx headers
* used to compile the code.
*
* This is a template declaration, but its only actual definition is a
* sepcialisation for the current library version. The definition is in the
* libpqxx binary, so it's based on the version as found in the binary. The
* headers contain a call to the function, specialised on the libpqxx version
* as found in the headers. (The library build process will use its own local
* headers even if another version of the headers is installed on the system.)
*
* If the libpqxx binary was compiled for a different version than the user's
* code, linking will fail with an error: @c check_library_version will not
* exist for the given version number.
