"""A Python driver for PostgreSQL
|
|
|
|
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.
