Guys, just so you know:
OSDL did some testing and found Ext3 to be perhaps the worst FS for PostgreSQL
-- although this testing was with the default options. Ext3 involved an
almost 40% write performance penalty compared with Ext2, whereas the penalty
for ReiserFS and JFS was less than 10%.
This concurs with my personal experience.
