Reviewers: JIRA, njain Changed the name of the stats table so that this update will apply automatically and immediately, otherwise the update command will fail on old schemas. Also introduced versioning to the name while I think is better than the old method of coming up with a new combination of (PARTITION, PART) and (STATISTICS, STATS).
