As I pointed out in my last email, he makes claims about PG being faster
than Oracle and MySQL based on his results. I've already pointed out
significant tuning considerations, for both Postgres and Oracle, which his
benchmark did not take into account.

This group really surprises me sometimes. For such a smart group of people,
I'm not sure why everyone seems to have a problem pointing out design flaws,
etc. in -hackers, yet when we want to look good, we'll overlook blatant
flaws where benchmarks are concerned.

One of these days I'll get some time and post my results. I'm just pointing
out obvious flaws in this benchmark. If Sergio wants to correct them and/or
qualify them, that's cool with me. I just don't like people relying on
questionable and/or unclear data.
