This is the point! You have to tell syslogd to log messages sent to this
facility. I prefer to log it to a different file than /var/log/messages.

As root do:

mkdir /var/log/postgresql/

Add something like

# postgresql
local0.*                          /var/log/postgresql/postgresql.log

to the end of your /etc/syslog.conf and do a

service syslogd reload

Make sure to add /var/log/postgresql/postgresql.log to the first line of
/etc/logrotate.d/syslog which is basically the list of syslog logfiles that
have to be regularly rotated .

On production servers with heavy load place use "-/var/log/postgr..." in
syslog.conf for a better performance. The - means  to uses buffered I/O.
