!     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
      by a dropped column immediately, the fastest way is:

!     The <literal>USING</literal> option of <literal>ALTER TYPE</> can actually
      specify any expression involving the old values of the row; that is, it
      can refer to other columns as well as the one being converted.  This allows
!     very general conversions to be done with the <literal>ALTER TYPE</>
      syntax.  Because of this flexibility, the <literal>USING</literal>
      expression is not applied to the column's default value (if any); the
      result might not be a constant expression as required for a default.
      This means that when there is no implicit or assignment cast from old to

      though a <literal>USING</literal> clause is supplied.  In such cases,
