psycopg is a PostgreSQL database adapter for the Python programming language (just like pygresql and popy.) It was written from scratch with the aim of being very small and fast, and stable as a rock. The main advantages of psycopg are that it supports (well, will support) the full Python DBAPI-2.0 and being thread safe at level 2. This requires postgresql and egenix-mx-base, both of which are available at SlackBuilds.org.
