I wouldn't actually add columns for that, but instead keep a copy of the
original record and compare its values again before inserting. Plus the
app needs to know which attributes can/should not be compared and can be
simply overwritten ("date last edited", "edited by" etc.).

Yes, I can imagine TG providing support for passing these values and
comparing them (maybe a special validator).

I've added this to http://trac.turbogears.org/ticket/2354 so it won't be
forgotten.
