rotating log files

Hi

What is a good solution for rotating postgresql log files?

I'm running 'Linux 2.2.16-22smp #1 SMP i686 unknown' and a solution that
was proposed to me was to use cron and a program called logrotate:

DESCRIPTION
       logrotate is designed to ease  administration  of  systems
       that generate large numbers of log files.  It allows auto­
       matic rotation, compression, removal, and mailing  of  log
       files.   Each  log  file  may  be  handled  daily, weekly,
       monthly, or when it grows too large.

Unfortunately, after replacing/rotating/compressing the database log file,
the new log file remains empty. I have a feeling that postgres has lost
the reference to the original log file and that the new log data is lost
into the void.

I'm curious what the consensus is about managing log files.
