I realized that any other solution here is going to be more complex and
thus less appropriate for backpatch. I still don't like this very much
because it doesn't seem to offer enough flexibility to user-specified
reloptions; but any patch we come up with here is going to be applicable
to CVS HEAD.

So I'm going to apply your patch to both 8.4 and HEAD; we can always
improve it later, I guess.
