Indeed, that's broken.  I guess we want pg_log_fatal then exit(1).

Seems plausible --- you want me to go change that?

That'd require adding an explicit init function and figuring out where to
call it, which we could do but I didn't (and don't) think it's worth the
trouble.  One more branch here isn't going to matter, especially given
that we can't even measure the presumed macro improvement.
