I'd be okay with that, except that pg_upgrade already has a pg_fatal
(because it has its *own* logging system, just in case you thought
this wasn't enough of a mess yet).  I'm in favor of aligning
pg_upgrade's logging with the rest, but I'd hoped to leave that for
later.  Making the names collide would be bad even as a short-term
thing, I fear.

Looks like libpq_pipeline.c has its own pg_fatal, too.

I'm not against choosing some name other than pg_log_fatal, but that
particular suggestion has got conflicts.  Got any other ideas?
