Django needs the following parameters for its database connections: You can configure them directly in postgresql. Django will work just fine without this optimization, but each new connection will do some additional queries to set these parameters.
If name is specified, the returned cursor will be a server side cursor also known as named cursor. Otherwise it will be a regular client side cursor. See Server side cursors.
The name can be a string not valid as a PostgreSQL identifier: Changed in version 2. Consider it as part of the query, not as a query parameter. The class returned should be a subclass of psycopg2.
See Connection and cursor factories for details. Closing a connection without committing the changes first will cause an implicit rollback to be performed.
The connection will be unusable from this point forward; an InterfaceError will be raised if any operation is attempted with the connection.
The same applies to all cursor objects trying to use the connection. Note that closing a connection without committing the changes first will cause any pending change to be discarded as if a ROLLBACK was performed unless a different isolation level has been selected: The command could have been sent to the backend at an inappropriate time, so Psycopg currently relies on the backend to implicitly discard uncommitted changes.
PgBouncer reports an unclean server and discards the connection. Exceptions as connection class attributes The connection also exposes as attributes the same exceptions available in the psycopg2 module.
