Mainly a bug fix. Also adds a preplacement for the functionality of
databases/py-pgnotify which no longer works with new versions of
PyGreSQL and PostgreSQL.
Fix a bug, introduced in version 3.7.15, that causes a segfault if the AS name of a result column of a SELECT statement is used as a logical term in the WHERE clause.
Changes since 4.0:
- Dropped support for Python below 2.5 and PostgreSQL below 8.3.
- Added support for Python up to 2.7 and PostgreSQL up to 9.2.
- Particularly, support PQescapeLiteral() and PQescapeIdentifier().
- The query method of the classic API now supports positional parameters.
This an effective way to pass arbitrary or unknown data without worrying
about SQL injection or syntax errors (contribution by Patrick TJ McPhee).
- The classic API now supports a method namedresult() in addition to
getresult() and dictresult(), which returns the rows of the result
as named tuples if these are supported (Python 2.6 or higher).
- The classic API has got the new methods begin(), commit(), rollback(),
savepoint() and release() for handling transactions.
- Both classic and DBAPI 2 connections can now be used as context
managers for encapsulating transactions.
- The execute() and executemany() methods now return the cursor object,
so you can now write statements like "for row in cursor.execute(...)"
(as suggested by Adam Frederick).
- Binary objects are now automatically escaped and unescaped.
- Bug in money quoting fixed. Amounts of $0.00 handled correctly.
- Proper handling of date and time objects as input.
- Proper handling of floats with 'nan' or 'inf' values as input.
- Fixed the set_decimal() function.
- All DatabaseError instances now have a sqlstate attribute.
- The getnotify() method can now also return payload strings (#15).
- Better support for notice processing with the new methods
set_notice_receiver() and get_notice_receiver()
(as suggested by Michael Filonenko, see #12 and #37).
- Open transactions are rolled back when pgdb connections are closed
(as suggested by Peter Harris, see #46).
- Connections and cursors can now be used with the "with" statement
(as suggested by Peter Harris, see #46).
- New method use_regtypes() that can be called to let getattnames()
return regular type names instead of the simplified classic types (#44).
- bug #3563824 [export] Support Apache's mod_deflate
- bug #3585523 [interface] Inline query editing broken after row update
- bug #3586389 [setup] Cannot switch language in /setup
- bug #3585695 [CSS] Font size in inline query editor is way too big
- bug #3588354 [l10n] Portuguese Language not displaying correctly
- bug #3591412 [status] Live charts don't work for non-default server
- bug [core] Proxy ajax calls to pma.net to avoid browser notices
- bug #3593534 [tracking] Structure Snapshot on tracked view renders
invalid SQL
- bug #3544366 [events] Event comments not saved
Approved by Thomas Klausner.

What's new in psycopg 2.4.6
---------------------------
- Fixed 'cursor()' arguments propagation in connection subclasses
and overriding of the 'cursor_factory' argument. Thanks to
Corry Haines for the report and the initial patch (ticket #105).
- Dropped GIL release during string adaptation around a function call
invoking a Python API function, which could cause interpreter crash.
Thanks to Manu Cupcic for the report (ticket #110).
- Close a green connection if there is an error in the callback.
Maybe a harsh solution but it leaves the program responsive
(ticket #113).
- 'register_hstore()', 'register_composite()', 'tpc_recover()' work with
RealDictConnection and Cursor (ticket #114).
- Fixed broken pool for Zope and connections re-init across ZSQL methods
in the same request (tickets #123, #125, #142).
- connect() raises an exception instead of swallowing keyword arguments
when a connection string is specified as well (ticket #131).
- Discard any result produced by 'executemany()' (ticket #133).
- Fixed pickling of FixedOffsetTimezone objects (ticket #135).
- Release the GIL around PQgetResult calls after COPY (ticket #140).
- Fixed empty strings handling in composite caster (ticket #141).
- Fixed pickling of DictRow and RealDictRow objects.

This is a pure Java (Type IV) JDBC driver for the PostgreSQL
database. It allows Java programs to connect to a PostgreSQL
database using standard, database independent Java code.
The driver provides a reasonably complete implementation of the
JDBC 4 specification in addition to some PostgreSQL specific
extensions.
