There are no events fired32    when a connection closes.33    For any given DB-API connection, there will be one ``connect``34    event, `n` number of ``checkout`` events, and either `n` or `n - 1`35    ``checkin`` events.  (If a ``Connection`` is detached from its36    pool via the ``detach()`` method, it won't be checked back in.)37    These are low-level events for low-level objects: raw Python38    DB-API connections, without the conveniences of the SQLAlchemy39    ``Connection`` wrapper, ``Dialect`` services or ``ClauseElement``40    execution.  If you execute SQL through the connection, explicitly41    closing all cursors and other resources is recommended.42    Events also receive a ``_ConnectionRecord``, a long-lived internal43    ``Pool`` object that basically represents a "slot" in the44    connection pool.  ``_ConnectionRecord`` objects have one public45    attribute of note: ``info``, a dictionary whose contents are46    scoped to the lifetime of the DB-API connection managed by the47    record.  You can use this shared storage area however you like.48    There is no need to subclass ``PoolListener`` to handle events.49    Any class that implements one or more of these methods can be used50    as a pool listener.  The ``Pool`` will inspect the methods51    provided by a listener object and add the listener to one or more52    internal event queues based on its capabilities.
