Use temp tables?

Also, it's likely that much of the WAL volume is full-page images.
While you can't safely turn those off in 8.1, you can dial down the
frequency of occurrence by increasing checkpoint_segments and
checkpoint_timeout as much as you can stand.  (The tradeoffs are
amount of space occupied by pg_xlog/ and time to recover from a crash.)
