Yes, that's been discussed before, and I think it's even got an entry
on the TODO list. If you've got time to tackle it now, great!
$PGDATA seems like the right place to put the file, since we can only
have one active postmaster at a time in a database directory.
I assume you'll also create a script that sends SIGTERM or other
requested signal to the postmaster, using this file?
