     1459.. warning::
     1460
     1461    Some Python database drivers, like ``psycopg2`` perform caching if using
     1462    client side cursors (the default). Using ``iterator()`` does not affect
     1463    caching at the database driver level. To disable this caching, look at
     1464    `server side cursors`_.
