Source Code for Package psycopg2

 1  """A Python driver for PostgreSQL 
 2   
 3  psycopg is a PostgreSQL_ database adapter for the Python_ programming 
 4  language. This is version 2, a complete rewrite of the original code to 
 5  provide new-style classes for connection and cursor objects and other sweet 
 6  candies. Like the original, psycopg 2 was written with the aim of being very 
 7  small and fast, and stable as a rock.
