I was wondering if the postmaster was running in some other data
directory than the OP thought. I've never heard of anything just
randomly removing a .pid file from a data directory; and it would
be extremely dangerous if that did happen, since the pidfile is the
main interlock against starting two postmasters in the same directory.
