So are other postmaster children, I believe. We could probably try
to rewrite the postmaster to not do useful work in signal handlers,
but rely on a lot of volatile flags set by the handlers. Not convinced
this would be anything but a cosmetic improvement, though. And it
could create new portability problems to replace any that it removed;
we'd have to be *absolutely* certain that the main select() call would
return with EINTR rather than resuming after any interrupt.
