That's very strange. The pg_ctl script itself doesn't delete
the postmaster.pid file under any circumstances (unless maybe
you are using a locally modified version?), and the postmaster
shouldn't delete it either unless exiting. Can you determine
exactly where the unlink call is coming from? strace or local
equivalent may help.
