I have tried to search for MySQL vs. PostgreSQL benchmarks and most of them date to 2007. Are there any recent benchmarks that compare these databases?

I personally use MySQL and I think it's an OK database (performance and installation wise) and I think it's a bit risky to jump on PostgreSQL when most others use MySQL (e.g. Flickr, Facebook, Yahoo, Google just to name a few).

Of note, Sun ironically performed a benchmark between PostgreSQL and Oracle. The results were that PostgreSQL performed very closely to Oracle under several scenarios.

It's not a direct comparison between MySQL, but Oracle is highly regarded from a performance standpoint.

Benchmarks between DBs are pretty rare because they are so difficult to control for. The configurations make a big difference. One set of benchmarks is here: http://tweakers.net/reviews/657/6 but thats in 2006. Also, MySQL has known fatal bugs in the production release so mysql isn't exactly a safe choice.

Outright FUD.
