It's deliberately undocumented (outside of the source code, that is).

Just thought I'd add that I've been using SQLAlchemy + Postgresql w/
psycopg2 driver with great success for a long time now. This is just a
preference, but I like using SQLAlchemy without the ORM. It has really good
support for basic low level stuff like defining tables, inserts and updates.

Why on earth would you want to? That'd be like translating Shakespeare

Hello list!
I'm having a strange issue, and I'm not entirely certain yet where
the actual problem is (ie, Python, PyGTK, or gtk+), but I figure I'll
start here. Bear with me, this'll probably be a long explanation...
I've been building an app which is meant to be run on both Linux and
Windows.
