Hi, Here http://www.westnet.com/~gsmith/content/postgresql/TuningPGWAL.htm I read: """ Combining these two, an optimal fstab for the WAL might look like this: /dev/hda2 /var ext3 defaults,writeback,noatime 1 2 """ Is this info accurate? I also read on other document from the "technical documentation" that for partitions where you have the tables and indexes is better to have journaling and for partitions for the WAL is better to not have journalling... i tought it has to be the other way (tables & indices without journalling, WAL with journalling) -- regards, Jaime Casanova Soporte y capacitación de PostgreSQL Guayaquil - Ecuador Cel.
