Please open a bug report and attach your patch (git format-patch is *perfect*) for review.

But first, rather than adding elements to the database, we generally add new fields with KVP,
which maintains backwards compatibility for the database. It would save an iteration or three
of "needs work" on your patch if you handle the persistence that way.
