Well, a "general principle" for which we already know one counterexample
isn't general enough for me.  The problem that I'm having here is that
it's not clear that there is any general solution, short of pg_dumpall
having variable-by-variable knowledge of which GUCs to set when, and
maybe even that wouldn't be good enough.
