Actually, now that I think a bit more, this isn't a good idea. We want
standby_signal_file_found (resp. recovery_signal_file_found) to get set
if the file exists, even if we're unable to fsync it for some reason.
A counterexample to the proposed patch is that a signal file that's
read-only to the server will get ignored, which it should not be.
