| It is best not to use SIGKILL to shut down the server. Doing so will
| prevent the server from releasing shared memory and semaphores,
| which may then have to be done manually before a new server can be
| started. Furthermore, SIGKILL kills the postmaster process without
| letting it relay the signal to its subprocesses, so it will be
| necessary to kill the individual subprocesses by hand as well.
