That's what happens every time I try it too.  The theoretical benefits 
of ext2 for hosting PostgreSQL just don't translate into significant 
performance increases on database oriented tests, certainly not ones 
that would justify the downside of having fsck issues come back again.  
Glad to see that holds true on this hardware too.
