Yeah, I think so. Keeping stability between minor
versions is a reasonable goal IMHO. I've only ever
seen one bug that would have triggered this condition
(the tdb update where the hash function was changed
due to a signed -> unsigned change).

DB format updates inside a minor release version
is a scummy thing to do to users (IMHO :-) and we
should really try not to do it.
