> 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.
