There are few if any GUCs that aren't exposed in headers, just so that
guc.c can communicate with the owning modules. That doesn't mean that
we want everybody in the world messing with them.
To my mind, we PGDLLEXPORT some variable only after deciding that yeah,
we're okay with having third-party modules touching that. Craig's
proposal is to remove human judgement from that process.
