Description:
Changes to the DD tables may mean that the DD version should be bumped. There is an MTR test catching this, but it should be improved, both in terms of checking for changes, and in terms of reporting what to do in case there is a change.

How to repeat:
.

Suggested fix:
Extend the dd_schema_definition_debug test to catch changes of the DD tables. The test should be written in a way that rejects batch recording of new result files.
