Update strong-migrations-enabled migrations from 5.0 and 5.1 to 5.2 (#24275) 2023-03-27 23:09:10 +09:00			`class MoreFasterIndexOnNotifications < ActiveRecord::Migration[5.2]`
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. 2018-01-05 03:38:29 +09:00			`disable_ddl_transaction!`
