Rather unrelated, but the tests here use the standard settings for
wal_buffers. As I have read on this list, 8.1 needs a much higher setting
for wal_buffers for good performance (128 or 256?). I don't know if you want
to change this setting because it will make the results incomparable, but it
should improve overall performance.
