Yes, review would be good :)

Apart from little syntax nitpicks though - the concept looks good.
One question: we can't tell easily if the DB is an old version I
don't think.  Would it make more sense to try to open it without
the upgrade flag first, and only if that fails to do the upgrade?

I'm thinking it would be good in that case to copy the file to a
temporary location and upgrade the temporary DB, then close it and
copy it back if the upgrade succeeds.
