Here's another nutty idea: Could one create a (carefully designed) audit
table on the system tables themselves? You'd need to exclude irrelevant
stuff (stats or whatever) & I'd have no idea about performance impact.
Dumping & transforming the audit would basically give you a script that
runs through all the actions done to a schema. I'm not 100% how to use
this for an update script though. I'm not sure a straight diff of
actions will work - it seems like the results may be order dependent in
some cases and you might need to infer undos. Anyway, it's interesting...
