Commit b87b135

0.9.3 released on 2010-01-01

----------------------------

* Fix inconsistency in savepoint identification by pq3.Transaction.

Savepoints via db.xact() were broken.

[Reported by Elvis Pranskevichus]

0.9.2 released on 2009-12-14

----------------------------

* Alter protocol message type comparison method.

In 0.9.1 and before, types were compared using 'is' because all

message type objects were loaded from a tuple created by the

postgresql.protocol.message_types module. In some environments,

sys.modules is cleared. For pure-Python installations, this is unlikely

to cause a problem, but when the optimized module is available, it will hold

a reference to the "old" version of the message_types data. Subsequently, the

use of the 'is' operator is then broken resulting in superfluous protocol

errors. The fix is to use the '==' operator. This does not add any

significant overhead, but use of 'is' may return if some permanent storage

method becomes available. [Reported by Radomir Stevanovic]

* Fix a bug revealed by a no route to host connection failure. Ended in an

ambiguous KeyError due there being no message string for that particular

errno. Add an appropriate message string, and fallback on a default message

when a specific one doesn't exist.

* Correct types.Array binary serialization (8.5 added extra checks)

* Add more encoding name mapping entries.

* Documentation improvements.

* Fix slice() support in Row.__getitem__.

* DEPRECATION: 2PC interfaces are being deprecated. Warnings in 1.0,

removal in 1.1.

0.9.1 released on 2009-08-12

----------------------------

* Fix misaligned reads in C extensions [Reported by Leonardo Francalanci]

* Don't be strict about keys(field type) in Notice messages per specification:

http://www.postgresql.org/docs/8.4/static/protocol-message-formats.html

* Fix test_protocol on ubuntu linux systems.

* Stop waiting for cluster startup on postgresql.exceptions.ProtocolError.

* DEAD BRANCH: 0.8 is no longer supported.

0.9.0 released on 2009-06-13

----------------------------

* Performance improvements.

* Extend `postgresql.open` to take keyword arguments.

* Implement query libraries and connection categories[#1010581 & #1010618].

* Implement ``clone()`` on Connections, Statements, and Cursors.

* Display the line and mark the location of the POSITION for syntax errors.

* Refactor ``ps.load()`` into ``ps.load_chunks()`` and ``ps.load_rows()``.

* Refactor `postgresql.api.InterfaceElement`.

* Refactor driver.pq3.Connection to use protocol.client3.Connection.

* Refactor driver.pq3.Cursor into types selected by PreparedStatements.

* Fix memory leak due to circular references and __del__. [Reported by Valentine Gogichashvili]

Additionally, try to avoid circular references at that level.

* Correct StoredProcedure's statement production. It was falsely using a

a mechanism that would use SQL predefined type names instead of

qualified names. [Reported by Dallas Morisett]

* Make DB-API connect() inherit defaults like postgresql.open()

* Make DB-API extend PG-API so that DB-API connections will now have direct

access to PG-API features.

* Fix DB-API setting of rowcount after execute. [Reported by Mike Bayer; 1010643]

* Document msghook attributes, and use postgresql.sys.errformat for

postgresql.exceptions.Error.__str__.

0.8.1 released on 2009-04-30

----------------------------

* Fix memory leak due to circular references and __del__. [Reported by Valentine Gogichashvili]

* Fix encoding normalization. [Reported by Marc Silver]

0.8.0 released on 2009-04-03

----------------------------

Differences from the original pg/python projects.

* Integrate projects into a single package. Remove "codenames".

* pg_greentrunk evolved into PG-API, postgresql.api.

* Add new execution methods to statement objects: chunks, rows, declare.

* Refactor connection negotiation code to use a generator. (xact3.Negotiation)

* Remove sixbit confusion from postgresql.exceptions.

* Integrate fcrypt module for crypt authentication.

* Remove pytz dependency, always use UTC for timestamptz.

* Remove netaddr dependency.

* Improve DB-API interface by allowing subjective paramstyle. (psycopg2 compat)

* Provide autocommit support on DB-API connections.

* Add support for binary numeric.

* Add proper support for sslmode and connect_timeout.

* Conditionally DECLARE certain cursors WITH HOLD when outside of blocks.

* Add typed support for fetches from db.cursor_from_id().

* Change the test infrastructure to automatically create a cluster.

* More improvements than I can remember.
