PostgreSQL and Journaled File Systems

Hi All,

What is the word about using PG with journaled file systems? I have heard
that it's best to not have the PG journal in a journaled system to avoid
double journaling.

Can someone that understand the issues involved (performance, reliability)
please shed some light on the issue?

Thanks in advance,

-Roberto
