  * contrib/rddads/adsx.c
    * implemented intermediate index creation in case ADS can process index
      FOR or WHILE condition.
      Ex., if requested index has WHILE condition supported by server,
      but index key expression is not supported (or codeblock is used),
      server side index is created using WHILE condition. This intermediate
      index later is used to create final index.
      This logic increases speed dramatically if WHILE condition was used
      to filter a few records from a large database using subindex.
