psycopg Python-PostgreSQL Database Adapter psycopg is a PostgreSQL database adapter for the Python programming language. 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 the full Python DBAPI-2.0, being thread safe at level 2 and providing some very usefull extensions like the user-defined type casters. psycopg is different from the other database adapter because it was designed for heavily multi-threaded applications that create and destroy lots of cursors and make a conspicuous number of concurrent INSERTs or UPDATEs. Every open Python connection keeps a pool of real (UNIX or TCP/IP) connections to the database. Every time a new cursor is created, a new connection does not need to be opened; instead one of the unused connections from the pool is used. That makes psycopg very fast in typical client-server applications that create a servicing thread every time a client request arrives. http://initd.org/pub/software/psycopg/psycopg-1.1.21.tar.gz Jeroen Ruigrok van der Werven ff1528b8febea3b8c864458751856bbf6ae88550 1.1.21
