-S is missing in postgresql.conf?

It has been declared evil, because it loses the log output. Using shell
redirection, or better yet pg_ctl is the way to go.

Really? I thought -S was evil because we had no working logging
facilities other than logging to stdout/stderr. Now we have the fixed
syslog functionarity, thus (at least part of ) the problem has gone.

Moreover if -S is still evil, why don't we completely remove -S? It
looks slightly inconsistent anyway.

IMHO we should make -S be configurable in postgresql.conf and let
users choose what they want.

I agree. Mind you, I think we should discourage use of -S, because it
makes troubleshooting so much more difficult. But we shouldn't remove
the option; people who are running a stable application mix and not
having problems may well think they don't need to expend disk space on
a postmaster log. And if we have the option then it ought to be
supported uniformly via GUC.

Ok. I have committed the changes. The name for the option in
postgresql.conf is "silent_mode" taking a value true or false (default
to false). If silent_mode is set to true, it would have a same effect
as -S of postmaser.
