It is one of many PostgreSQL interfaces for the Python programming language. pg8000 is somewhat distinctive in that it is written entirely in Python and does not rely on any external libraries (such as a compiled python module, or PostgreSQL’s libpq library).
This pure-python connector approach allows to run it where C compiled libraries cannot be installed, it allows deeper access to PostgreSQL protocol internals and it enables easier flexibility and extensibility for Python developers (like support for parameterized prepared statements using qmark, numeric, named, format or pyformat DBAPI paramstyle).
The highlights of this 1.09 maintenance release are: two-phase commit support, autocommit feature, server_version property and bug fixes for almost all reported issues since 1.08 (2010-06-08)

PS: I've been working with this library since the last year, it helped me where psycopg2 couldn't be installed (dependency compilation issues in older systems) or when I needed more flexibility (i.e. paramstyle). As it seems that the original author don't maintain it anymore, I've decided to make a fork in googlecode, with the hope it could be useful to other people too.
