Raw vs Filesystem

Hello Jaime,

I think you're on the right track but have gotten some
concepts possibly confused.

As I remember, the original email asked if Postgres
could be run in a "raw" mode. Another submitter
told us that it can not. ( Did I read that correctly, everyone ? )

This means run Postgress in a raw or character mode versus
the "standard" block mode as you would handle other files
in a filesystem. The primary advantage for a raw mode
is speed. ORACLE allows this method of operation.

So ... your last question is now rather moot. For best
performance assure your setup parameters and Linux
kernel parameters are optimized. Help with that
is a few keystrokes from anywhere.
