In order to migrate MySQL and Sqlite to abstract schema changed the tl_title data type from varchar binary to varbinary. This wouldn't affect production. For migrating Postgres: - Dropping foreign key on tl_from - Changing data type of tl_namespace from SMALLINT to INT and setting its default - Setting default of empty string for tl_title - Completely rewriting indexes to make it synced with MySQL Bug: T164898 Bug: T230428 Change-Id: Idbb65d870f58f7146b9c8bd860e6530bef1e0f12
