Perhaps it should be tied to bumping the major version number, which I'm
guessing would happen next whenever we get parallel query execution. If
we do that, a reasonable policy might be that a compatability GUC lives
across no more than 1 major version bump (ie, we wouldn't remove
something in 9.0 that was added in 8.4).
