       The type <type>integer</type> is the common choice, as it offers
       the best balance between range, storage size, and performance.
       The <type>smallint</type> type is generally only used if disk
!      space is at a premium.  The <type>bigint</type> type should only
!      be used if the range of the <type>integer</type> type is insufficient,
!      because the latter is definitely faster.

!      On very minimal operating systems the <type>bigint</type> type
!      might not function correctly, because it relies on compiler support
!      for eight-byte integers.  On such machines, <type>bigint</type>
!      acts the same as <type>integer</type>, but still takes up eight
!      bytes of storage.  (We are not aware of any modern
!      platform where this is the case.)
