+ * (the role which is running the query or the value of the row_security
+ * GUC), or it might be simply enabled as usual.
+ *
+ * If RLS isn't on the table involved then RLS_NONE is returned to indicate
+ * that we don't need to worry about invalidating the query plan for RLS
+ * reasons.  If RLS is on the table, but we are bypassing it for now, then
+ * we return RLS_NONE_ENV to indicate that, if the environment changes,
+ * we need to invalidate and replan.  Finally, if RLS should be turned on
+ * for the query, then we return RLS_ENABLED, which means we also need to
+ * invalidate if the environment changes.
+ *
+ * Note that RLS_ENABLED will also be returned if noError is true
+ * (indicating that the caller simply want to know if RLS should be applied
+ * for this user but doesn't want an error thrown if it is; this is used
+ * by other error cases where we're just trying to decide if data from the
+ * table should be passed back to the user or not).
