Good point. For DROP TABLE/ALTER TABLE, I need to take care of its chidren.

Just a suggestion, but...
Why not using an external wrapper function on reportDependentObjects in
dependency.c to find the list of Oids for a cascade deletion based on a list
of objects?
Isn't it possible?

Hi,
I'm working on implemeting query cache for pgpool-II. The query cache
must be deleted if related tables are dropped. Finding tables oids
from DROP TABLE t1, t2, t3... is easy. Problem is DROP TABLE
CASCADE. It seems there's no easy way to find table oids which will be
deleted by DROP TABLE CAS
