      There are some bugs about backward scanning using · 174b552e

      indexes.
      
      1. Index Scan using plural indexids never scan backward
         as to the order of indexids.
      2. The cursor using Index scan is not usable after moving
         past the end.
      
      This patch solves above bugs.
      Moreover the change of _bt_first() would be useful to extend
      ORDER BY patch by Jan Wieck for all descending order cases.
