Umm... backends have already used SIGUSR1. PostgresMain() sets up a signal handler for SIGUSR1 as follows.
Uh.. right. Thanks for pointing that out. Maybe just use SIGPIPE for now?
Yes, since WAL sender waits on select(), it's convenient to use signal for the notification *from backends to WAL sender*, I think too.
..and I'd say you better use the same for WAL sender to backend communication, just for the sake of simplicity (and thus maintainability).
