PostgreSQL 6.5.3 log

Hi! Dear List!

I use the postgresql-6.5.3 and I 've a problem. The server works correctly, but
doesn't log to the log file.
I create the '/var/log/postgresql' file and give 'chown postgres.postgres'and
'chmod 0700 postgresql'.
I wrote to the postgres user's '.bash_profile' file:
POSTGRES_LOG=/var/log/postgresql
PGDEBUG=9
export POSTGRES_LOG PGDEBUG

But the postgresql doesn't log to that file. Why? What should I do?

Please write to my private mail address, because I didn't subscribe (mailing
list). :-)
THanx!!

Bye!
