In order to migrate MySQL and Sqlite to abstract schema changed the pl_title data type from varchar binary to varbinary. This wouldn't affect production. For migrating Postgres: - Dropping foreign key on pl_from - Changing data type of pl_namespace from SMALLINT to INT and setting its default - Setting default of empty string for pl_title - Completely rewriting indexes to make it synced with MySQL Bug: T164898 Bug: T230428 Change-Id: I4af8202742a1826e6b3f8ff36cf4f7b612b82690
