example:
$ create schema x;
CREATE SCHEMA
$ create table x.y as select * from pg_class;
SELECT 294
$ explain select * from x.y limit 1;
                         QUERY PLAN                         
------------------------------------------------------------
 Limit  (cost=0.00..0.04 rows=1 width=189)
   ->  Seq Scan on y  (cost=0.00..13.70 rows=370 width=189)
(2 rows)
Why it doesn't show "Seq Scan on x.y" ? it makes certain plans virtually
useless, when you can't know which schema was used?!
