Agreed. You can't argue with a well executed benchmark. All I'd say is be careful not just the same simple select statement over and over again - Do a variety of both simple and complex queries. And always use InnoDB as compared to MyISAM (otherwise you're not comparing apples with apples). The biggest pro (imho) that PostgreSQL has over MySQL is its locking mechanism. PostgreSQL uses MVCC, which greatly improves concurrency.
