rotatelog / logrotate with PostgreSQL

Howdy:

Running PostgreSQL 7.2.1 on RedHat Linux 7.2 kernel 2.4.7.

Can someone send an example of how they have the 
logrotate / rotatelog script working with PostgreSQL?
I'm looking at a few things and I can't seem to
get it to work.

Also, is there an easy way to tell if PostgreSQL have
been configured with "--enable-syslog"?  If I have that,
then I can just use the syslog.conf and collect logs 
that way.

Thanks!
