Patch or otherwise, this approach seems totally unworkable. A signal
handler cannot do I/O safely, it cannot look at shared memory safely,
it cannot even look at the backend's own internal state safely. How's
it going to do any useful status reporting?
Firing up a separate backend process that looks at shared memory seems
like a more useful design in the long run. That will mean exporting
more per-backend status into shared memory, however, and that means that
this is not a trivial change.
