What would guarantee that the OIDs of those rows don't conflict with
some other OIDs in the system?

BTW, this becomes a real issue if you're trying to write code that is
meant to be incorporated into other PostgreSQL applications, which might
also be using user_lock. Having a text-based means to identify locks
greatly reduces the odds of conflicting with a userlock being used by an
existing application.
