I'm surprised you get any error message at all (as seen by a client,
that is, not as seen in the postmaster log). AFAICT, backend libpq
is not fired up until well down inside PostmasterMain --- look at the
call to pq_init. Until that's done, it's impossible to send error
messages to the client. I've been meaning to look at whether the
pq_init call couldn't be moved up to before (instead of after) option
and switch processing ...
