I am more than happy to essentially just copy & paste some code that
will be specific to pgbench if that is preferrable for the purposes of
merging this patch. Another idea would be to change the signature of
setup_cancel_handler() to something like:
void
setup_cancel_handler(cb pre, cb post, int signal, ...); (null-terminate)
Then a client could state exactly what signals it wants to register with
this generic cancel handler.
