This question has been answered very ably by a lot of other people. What I really want to know is why we get a version of this every time there's a thread about MySQL here. I used to use MySQL, now I'm mostly using MS SQL, I could give a dissertation about what I don't like and do like about each relative to the other. When I go into a Postgres thread, I'm mostly looking to learn about Postgres. It feels like whenever Postgres users come into a MySQL thread, it's to score points. It's annoying and it gives a really poor impression of the Postgres community.
Thanks for pointing this out, I agree it's tacky. Unfortunately this sort of thing seems to be part of nerd culture. I know it's gotten bad when I have a serious urge to sidetrack PostgreSQL threads with MySQL related trolling, but participating will only make things worse.
I'm sure PHP (and to a lesser extent GNU Screen) enthusiasts know what this feels like. It's as easy as painting a bike shed to point out ways that these tools suck, they all have some historical baggage and warts.
