I think this will do the job; can you please check it out:
select rcname,rcsrc from pg_relcheck, pg_inherits as i
where rcrelid = '%s'::oid
and (not exists -- for
(select * from pg_inherits -- non-inherited
where inhrel = pg_relcheck.rcrelid) -- tables
or (not exists --
(select * from pg_relcheck as c -- for
where c.rcname = pg_relcheck.rcname -- inherited
and c.rcrelid = i.inhparent) -- tables
and rcrelid = i.inhrel)); --
--
