One concrete reason not to do the proposed trivial hack is that the lock
readout views are asynchronous. Right now, if someone sees a process that
claims to be waiting but they don't see any entry in pg_locks, they know
they saw inconsistent state. If we add a valid state where waiting can be
true without a pg_locks entry, they won't know what to think. I don't
want to go there.
FWIW, I really wish we had a way to eliminate that inconsistency. It makes
already difficult to debug problems even harder to deal with.
