A quick suggestion from a passer-by -- would you put the new code in
src/backend/storage/ipc/backend_signal.c instead?  Sounds like a better
place than utils/misc/; and "signal" is more general in nature than just
"cancel".  A bunch of stuff from utils/adt/misc.c (???) can migrate to
the new file -- everything from line 201 to 362 at least, that is:

pg_signal_backend
pg_cancel_backend
pg_terminate_backend
pg_reload_conf
pg_rotate_logfile

Maybe have two patches, 0001 creates the files moving the contents over,
then 0002 adds your new stuff on top.

/me wonders if there's anything that would suggest to make this
extensive to processes other than backends ...
