In order to migrate MySQL and Sqlite to abstract schema changed the il_to data type from varchar binary to varbinary. This wouldn't affect production. For migrating Postgres: - Dropping foreign key on il_from - Setting default of empty string for il_to - Completely rewriting indexes to make it synced with MySQL Bug: T164898 Bug: T230428 Change-Id: I59f0d0a56d938a168bf1c7de2a1be47f15d1add1
