That is not correct assumption. A journalling file system ensures file system 
consistency even at a cost of loss of some data. And postgresql can not 
guarantee recovery if WAL logs are corrupt. Some months back, there was a 
case reported where ext2 corrupted WAL and database. BAckup is only solution 

Journalling file systems are usually very close to ext2 in performance, many a 
times lot better. With ext2, you are buying a huge risk.

Unless there are good reason, I would not put a database on ext2. Performance 
isn't one ofthem..
