From now on, PostgreSQL should start automatically each time you boot
up and it should shutdown gracefully each time you shut down. (Note:
Debian defaults to starting all services on runlevels 2-5. Red Hat
defaults to starting services on 3-5. So, on Red Hat, PostgreSQL won't
start on runlevel 2 unless you alter the above commands a
little. This usually isn't a problem as Red Hat defaults to runlevel 3)
