-- This script upgrades the Sqitch registry for MySQL 5.6.4 and higher. Sqitch
-- expects datetime columns to have a precision on 5.6.4 and higher. If you have
-- an existing Sqitch registry that was upgraded from an earlier version of MySQL
-- to 5.6.4 or higher, you'll need to run this script to update it, like so:
--      mysql -u root sqitch --execute "source `sqitch --etc`/tools/upgrade-registry-to-mysql-5.6.4.sql'
