What does that have to do with this?
Two different oids represents two different objects, right?
Two different objects should have two different descriptions, right?
Otherwise I cannot see how one can argue the description being unique.
The pg_describe_object returns unique descriptions for all object
types, except for the 5 types I unexpectedly found.
