I think it depends. As an example, maybe_start_bgworker is called
from PostmasterMain, *and* from ServerLoop, *and* from reaper,
*and* from sigusr1_handler. That's likely excessive, but it's what
we've got at the moment.
I'm pretty sure regular backends are only launched from ServerLoop,
but for anything else it's uncertain.
