This function is part of the `DBAPI 2.0 specification
`_; however, the arguments of the
function are not defined by the specification.
:param user:
The username to connect to the PostgreSQL server with.
If your server character encoding is not ``ascii`` or ``utf8``, then
you need to provide ``user`` as bytes, eg.
``"my_name".encode('EUC-JP')``.
:keyword host:
The hostname of the PostgreSQL server to connect with. Providing this
parameter is necessary for TCP/IP connections. One of either ``host``
or ``unix_sock`` must be provided. The default is ``localhost``.
:keyword unix_sock:
The path to the UNIX socket to access the database through, for
example, ``'/tmp/.s.PGSQL.5432'``. One of either ``host`` or
``unix_sock`` must be provided.
:keyword port:
The TCP/IP port of the PostgreSQL server instance. This parameter
defaults to ``5432``, the registered common port of PostgreSQL TCP/IP
servers.
:keyword database:
The name of the database instance to connect with. This parameter is
optional; if omitted, the PostgreSQL server will assume the database
name is the same as the username.
If your server character encoding is not ``ascii`` or ``utf8``, then
you need to provide ``database`` as bytes, eg.
``"my_db".encode('EUC-JP')``.
:keyword password:
The user password to connect to the server with. This parameter is
optional; if omitted and the database server requests password-based
authentication, the connection will fail to open. If this parameter
is provided but not requested by the server, no error will occur.
If your server character encoding is not ``ascii`` or ``utf8``, then
you need to provide ``user`` as bytes, eg.
``"my_password".encode('EUC-JP')``.
:keyword ssl:
Use SSL encryption for TCP/IP sockets if ``True``. Defaults to
``False``.
:keyword timeout:
Only used with Python 3, this is the time in seconds before the
connection to the database will time out. The default is ``None`` which
means no timeout.
:rtype:
A :class:`Connection` object.
