Don't know what you're looking at, but the GUC is definitely there (and
documented) in 8.2.

Is it time to remove this GUC?

Perhaps, but I'd like to have a less ad-hoc process about it.  What's
our policy for dropping backwards-compatibility GUCs?  Are there any
others that should be removed now as well?

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).
