Fix connections possibly left in the pool after closing (ticket #784).

Current release#

psycopg_pool 3.2.1#

Respect the timeout parameter on connection() when check fails. Also avoid a busy-loop of checking; separate check attempts using an exponential backoff (ticket #709).
Use typing.Self as a more correct return value annotation of context managers and other self-returning methods (see ticket 708).

psycopg_pool 3.2.0#

Add support for async reconnect_failed callbacks in AsyncConnectionPool (ticket #520).
Add check parameter to the pool constructor and check_connection() method. (ticket #656).
Make connection pool classes generic on the connection type (ticket #559).
Raise a warning if sync pools rely an implicit open=True and the pool context is not used. In the future the default will become False (ticket #659).
Raise a warning if async pools are opened in the constructor. In the future it will become an error. (ticket #659).

Fix the return type annotation of NullConnectionPool.__enter__() (ticket #540).
