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 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") Or as a mix of both. The basic connection parameters are: - *dbname*: the database name - *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. *async_* is a valid alias (for Python versions where ``async`` is a keyword). Any other keyword parameter will be passed to the underlying client library: the list of supported parameters depends on the library version. asyncZasync_connection_factoryN)pop_extZmake_dsnrcursor_factory)Zdsnr!r$kwargsZkwasyncconnr'T/var/www/html/llm_bihealth/app/venv/lib/python3.9/site-packages/psycopg2/__init__.pyconnectPs#r))NNN)*__doc__Zpsycopg2._psycopgrrrrrrrr r r r r rrrrrrrrrrrrrrrrZpsycopg2rr#Zregister_adaptertupleZSQL_INtypeZ NoneAdapterdecimalrZAdapterr)r'r'r'r(s2x
