First thought is make sure you are looking in the right database.
pg_locks shows data over the entire server, not just the connected database.
pg_class exists for each database so if you are connected to 'my_database' but the object is in 'your_database', it
won'tshow up in pg_class on 'my_database'.
check the database value in pg_locks to verify where you should be looking for the object.
