Actually, the folks over at http://tweakers.net recently benchmarked
MySQL and PostgreSQL with their website code. IIRC, this is mostly
"simple selects", yet PostgreSQL clearly outperformed MySQL once you
had a few concurrent connections happening.

My experience is that the only places you'll readily see MySQL
outperform PostgreSQL is when you're only using a single connection,
and probably not with complex queries.

Of course, the first rule of benchmarking is to use your own
application.
