pg8000 is a DB-API 2.0 compatible Pure-Python interface to the PostgreSQL database engine. 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).
pg8000 is available for Python 2.5 and 2.6 (and likely future 2.x releases); an actively maintained and fully functional Python 3 branch of pg8000 called pg8000-py3 is also available.
pg8000’s name comes from the belief that it is probably about the 8000th PostgreSQL interface for Python. pg8000 is distributed under the terms of a modified BSD license.
The latest release of pg8000 is version 1.08, released on June 8th, 2010.
