Changing the states of the GUC tables in the stable branches would be
OK in this case.  Now, it took so many years for somebody to complain
that setting huge pages at 1TB on a 32b build does not work that I
cannot really get excited about a backpatch.  So I would just do the
switch on HEAD, and call it a day.
