Use disable_ddl_transaction! to prevent warnings on migration (#6183) Migration is wrapped by transaction, so manual `commit_db_transaction` without transaction restarting causes "there is no transaction in progress" warnings. We should use `disable_ddl_transaction!` instead, if we can omit transaction completely. 2018-01-04 18:38:29 +00:00			`disable_ddl_transaction!`
