Hmm, AFAICS the problem with controldata is that it uses postgres_fe.h
instead of postgres.h. It's a bit of a stretch to use the latter, but
maybe that's a better solution? After all, it *is* poking into the
backend internals.
I know I had to hack around pg_controldata some time ago (I don't recall
what for) and found that it could be cleaned up like this.
