Robert and I just discussed this subproblem (the original complaint of
this thread) off-list.  Our questions are: does anyone actually want
that message from the postmaster in the log, and if not, shouldn't we
just do this?

                return true;
        }

As for the problem of the behaviour of bgworker processes themselves
on SIGTERM, let's discuss that separately in the other subthread[1]
(well, my mail client thinks it's a different thread, but the archives
think it's the same thread with a different subject).
