DatabaseUpdater は、データベースの更新処理 (例: テーブル、フィールド、インデックスの、追加、変更、削除) を扱うクラスです。 MysqlUpdater.php , PostgresUpdater.php , and SqliteUpdater.php extend this class, and all of those files (as well as the tables.sql files for the various database types) potentially need to be revised when a core schema change is made. Extensions usually change the schema by means of LoadExtensionSchemaUpdates hook functions. Either way, SQL patch file(s) need to be created.
