Seems reasonable to me.

Yeah, that's fine. I think though that I may have created a bug inside
GUC itself: the new stacking code could conceivably fail (palloc error)
between success return from the assign hook and setting up the stack
entry that is needed to undo the assignment on abort. In this situation
the assign hook would've made its "other thing" changes but there is no
GUC state to cause the hook to be called again to undo 'em. I need to
fix it so that any palloc'ing needed is done before calling the assign
hook.
