Well, in my experiences with MySQL and Postgres, MySQL servers have a real annoying tendency to always go down, as it's greatness is dwindling away, while Postgres is emerging to be very great. I was reading up on a few articles, and decided to use it on my own computer, and man, the server load lightened like crazy. Anyhow, I know that it does not support it (yet?), but are the dev's working on it, because I am getting dead sick of MySQL.
