BTW, I cannot find any evidence that our old Bonjour code doesn't work
on Snow Leopard: it compiles, with just the same deprecation warning
as before, and the postmaster runs, and you can see the Bonjour
registration appear with something like 'dns-sd -B _postgresql' ---
and disappear again when the postmaster exits. I had guessed that
Jerry LeVan's DNS issues might be somehow related to this code, but
apparently not.
So I'm inclined to change the code now that we've got a replacement
that doesn't cause the deprecation warning, but there doesn't seem to
be any need to back-patch it.
I will also see about adding a separate boolean control GUC, as
discussed.
