That's not a bug.  On SIGKILL the postmaster does not send down the
message to its subprocesses.  Note as well that shared memory is not
released as well, so you may need to kill any extra orphan process
remaining alive after the postmaster is down, so that's not a
recommended way to stop the instance.
