It's not really easy, you need to get the references information out of
pg_trigger (see the archives for more information) and then given that
you could probably formulate the query necessary to get the rows (you'd
probably want to look at backend/utils/adt/ri_triggers.c at the noaction
triggers for information on how to make the query).

TIP 2: you can get off all lists at once with the unregister command
