Logfile permissions

Hi,

my logfiles all have this permission:

-rw------- 1 postgres postgres 14841 10. Feb 08:52
postgresql-2009-02-10_000000.log

Is it possible that postgres creates group readable files? I want to
monitor this logfile, but
for security I don't want to use the postgres user for this.

I looked at this documentation and could not find a solution:
http://www.postgresql.org/docs/8.2/static/runtime-config-logging.html

I use this settings:

log_destination = 'stderr'
redirect_stderr = on

Since the server is linux, I could use syslog, too. But somehow I want
to stay with the defaults (SuSE).

How do you check your logfiles?
