> The {{system.schema_columns}} table contains the "denormalized" description
> of the user type its {{validator}} column.
> But if the type is changed after a column using that type has been created,
> the column's {{validator}} column still contains the old (and now incorrect)
> description of the user type.
> This gets even more complicated if user types are embedded in other user
> types...
