Add note warning users that Postgres' port number is forced in the service
file, mainly because it's traditional in Red Hat installations to set it
there rather than in postgresql.conf. (There are minor usability benefits
to doing it this way though, for example that the postmaster's port number
is visible in "ps" as part of its command line.)
