listen/notify with python pgdb

[postgresql 7.3, python 2.3a1, pygresql-3.4-pre021201]
Does anyone use listen/notify with pgdb, the python DB-API
interface? I've done a crude hack, but maybe someone has a nicer one?
{Yes, I know notify is not part of the python DB-API: I'm trying
to stay as close to portable API's and still get the work done...}

Here's what I'm doing:
#pgdb_extended.py
'''This is a small wrapper module for pgdb, the Python DB-SIG 2.0
compliant implentation for postgresql access from python.
This wrapper adds just one member function, viz. 'pgdbCnx.getnotify()'.
getnotify just calls the postgresql libpq C API function getnotify() to
get notify messages resulting corresponding to sql 'listen' commands that
have been made.'''

from pgdb import *

def getnotify(self):
return self._pgdbCnx__cnx.getnotify()

pgdbCnx.getnotify = getnotify
