   3  * Alternate 1.4 -> 1.5 schema upgrade.
   4  * This does only the main tables + UTF-8 and is designed to allow upgrades to
   5  * interleave with other updates on the replication stream so that large wikis
   6  * can be upgraded without disrupting other services.
   7  *
   8  * Note: this script DOES NOT apply every update, nor will it probably handle
   9  * much older versions, etc.
  10  * Run this, FOLLOWED BY update.php, for upgrading from 1.4.5 release to 1.5.
