True for a Python object, but not for a C extension object. But
subclassing is supported, so one would be able to do:
>>> class MyConnection(psycopg2.extensions.connection):
... _get_native_connection =
psycopg2.extensions.connection.get_native_connection
...
>>> cnn = psycopg2.connect('', connection_factory=MyConnection)
>>> ptr = cnn._get_native_connection()
