!     The fact that <literal>ALTER TYPE</> requires rewriting the whole table
      is sometimes an advantage, because the rewriting process eliminates
      any dead space in the table.  For example, to reclaim the space occupied

!     The <literal>USING</literal> option of <literal>ALTER TYPE</> can actually

      expression is not applied to the column's default value (if any); the
