That was proposed and rejected quite a long time ago. We don't *want*
people to be able to "just change a GUC" and have their xlog go
somewhere else, because of the foot-gun potential. You need to be sure
that the existing WAL files get moved over when you do something like
that, and the GUC infrastructure isn't up to ensuring that.
