I wouldn't bet on it. Even MySQL's own benchmark page shows Postgres 6.5
beating MySQL for selects with JOIN, quite handily. Since real-world
database usage depends heavily on JOINs I wouldn't be surprised if the
standard benchmark used by Xperts contains lots and lots of joins,
which would tend to make MySQL run slow.
MySQL is good at one thing, and one thing only: running simple queries
in single-user mode.

That's how the normal TPC testing is done, I believe. Except on huge
honkin' hardware.
