Hi Eric,

I am trying your code. I will put a revised version
on the patch tracker, so that future discussions about it
are easier to follow.

The first things I modified are:

- add a hidden db variable to the form, to propagate db
- remove the call to PMA_SQP_analyse (what did you want to do with this?)
