leifbk writes "'The Web is broken and it's all your fault' says Rasmus Lerdorf, the creator of PHP. He talks about not trusting user input, and the brokenness of IE, which is all fine. Then he makes a statement about MySQL vs PostgreSQL: 'If you can fit your problem into what MySQL can handle it's very fast,' Lerdorf said. 'You can gain quite a bit of performance.' For the items that MySQL doesn't handle as well as PostgreSQL, Lerdorf noted that some features can be emulated in PHP itself, and you still end up with a net performance boost. Naturally, the PostgreSQL community is rather unimpressed. One of the more amusing replies: 'I wasn't able to find anything the article worth discussing. If you give up A, C, I, and D, of course you get better performance- just like you can get better performance from a wheel-less Yugo if you slide it down a luge track.'"
