"""Python-PostgreSQL Database Adapter
psycopg is a PostgreSQL database adapter for the Python programming
language. This is version 2, a complete rewrite of the original code to
provide new-style classes for connection and cursor objects and other sweet
candies. Like the original, psycopg 2 was written with the aim of being
very small and fast, and stable as a rock.
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. psycopg 2 also provide full asycronous operations for the really
brave programmer.
