Well, there are corner cases where the object OID gets reused during
the lifetime of the transaction, and then the lock *does* do something
(and what it does would be bad). But taking up extra space in the
finite-size lock table is sufficient reason IMO to drop the lock.
It's not like these are performance-critical code paths.
