Catering for postgres and mysql

[tomglare]

It would be a bonus to maintain postgres connectivity if someone can devote themselves to it, but I am not sure if the demand for postgres justifies making it a major priority. Like many people, I would not have touched mysql when it first appeared because it had little inbuilt integrity, in particular lacking foreign keys, but for most purposes it has since caught up with postgres. I still much prefer postgres, particularly the command line tools, but can not afford to spend too much time swimming against the tide.
