I was actually through that code months ago, wondering why (ahem)
PG was so stupid about disk I/O and reached the same conclusion.

Therefore, I was more than pleased when a simple fix to get rid
of fsync's on read-only transactions arose.  In my application
space, this alone gave a huge performance boost.

WAL...that's it.  If Vadim is going to be unavailable because
of his new job, we'll need to figure out another way to do it.
