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));                     --
