I left the statistic setting as-is (do you think that's wrong?) but the
storage spec gets reset to whatever the default for the new type is.
We could talk about doing something more complicated, such as "keep the
old setting if both old and new types support toasting, else reset to
new default".  Not sure if that'd be better or not.
