PostgreSQL driver for Joomla review

If anyone has a moment, could they review the PostgreSQL driver I
wrote for Joomla's next major release?  The developers at Joomla have
listened to the persistent noise created about only having MySQL as an
option and are now accepting submissions for alternative database
systems. (see http://groups.google.com/group/joomla-dev-cms/browse_thread/thread/1382dc6f4af56278#msg_9b95648941ef6fa7
for this development)

My submission can be found at:
http://joomlacode.org/gf/project/joomla/tracker/?action=TrackerItemEdit&tracker_item_id=18384

Things to watch out for a version-dependent features and clumsy implementations.

Thanks

Thom Brown
