I have to say that randomly creating DB schemas and then reengineering
them is probably the weirdest, but also coolest thing I've ever heard of.
Welcome Andriy! :-)
Keeping this regression suite in parallel to the regular unit tests is a
very good idea. A simple 'regression' ant target would be nice to have,
later.

I might be missing something but one thing I'd like to see is a kind of
pluggable PKFactory that allows me to quickly provide new per-entity PKs
without exposing the attribute on the DataObject. Something along the
lines of EOF's EOAdaptorChannel.primaryKey(s)ForNewRowWithEntity. Is this
what you have in mind, too? Especially for DBs that can handle the special
unique-24-byte-PK the performance is just so much better and solves many
PK related race conditions with multiple writers.
