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.
