That's an interesting insight. I took a closer look at the actual
metadata changes I mentioned in my first post. Apart from a few fields,
which got assigned default values, there doesn't seem to be anything
that could affect database size after restore. No field size changes at all.
But thanks for this suggestion anyway, it's worth remebmering that
changing the type doesn't affect the data that's already there.
