    Description

      Implement SYSCS_UTIL.UPDATE_STATISTICS by having the ALTER TABLE code use the new istat daemon in explicit mode.
      Doing this will allow for a period of limited exposure before the background mode of the daemon is enabled, and it will verify that the code generating the index statistics is working.
