It's strange that pg_identify_object returns empty type in only some
cases (as seen in the regression test output) ... and this one
definitely does not make sense:

+SELECT * FROM pg_identify_object('pg_class'::regclass, 'pg_class'::regclass, -8); -- no column for relation
+ type | schema | name | identity
+--------------+------------+----------+---------------------
+ table column | pg_catalog | pg_class | pg_catalog.pg_class
+(1 row)
