PGFSYNC=no in postmaster.init?

Well, this might be Debian Linux specific, pardon me if it is. I have
just begun playing with Postgres. Still learning, myself.

IOW, disable fsync after every statement and your OS will do much
better work clustering writes. That means more inserts/sec for you.

In one of my tests I was able to insert at ~1000/sec rate. Then I made
an experiment, enabled pgfsync _and_ indexes. The inserting speed
dropped to 10/sec. Very interesting.
