DatabaseUpdater is the class for handling database updates (e.g. adding, modifying, and dropping database tables, fields, and indexes). 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.
