Auto-change of structure we have discuss few times...

Everything is not so simple.

What to do if you have REMOVE field?
Remove field from db ?

In fact we have add Table.ID and Field.ID think about such tasks!
Because now we have ability to see what fields was added, what removed, and
what changed.

But it needs yet do some work I think ...
