Dunno ... I cannot recall ever having had that as a debugging requirement
in a couple of decades worth of PG bug-chasing.  If the postmaster is
dying, you generally want to deal with that before bothering with child
processes.  Moreover, child processes that don't go awy when the
postmaster does are a very nasty problem, because they could screw up
subsequent debugging work.
