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.

The connection parameters can be specified either as a string: conn = psycopg2.connect("dbname=test user=postgres password=secret") or using a set of keyword arguments: conn = psycopg2.connect(database="test", user="postgres", password="secret") The basic connection parameters are: - *dbname*: the database name (only in dsn string) - *database*: the database name (only as keyword argument) - *user*: user name used to authenticate - *password*: password used to authenticate - *host*: database host address (defaults to UNIX socket if not provided) - *port*: connection port number (defaults to 5432 if not provided) Using the *connection_factory* parameter a different class or connections factory can be specified. It should be a callable object taking a dsn argument. Using the *cursor_factory* parameter, a new default cursor factory will be used by cursor(). Using *async*=True an asynchronous connection will be created. Any other keyword parameter will be passed to the underlying client library: the list of supported parameters depends on the library version.
