The join conditions are far from adequate. You can *not* just check the
objid, you *must* check classid (and refclassid) to avoid being fooled
by duplicate OIDs in different system catalogs. You've also not held
to psql's normal conventions about fully qualifying names to avoid
making assumptions about the search_path.
