Changing the column type in this existing migration file won’t update already-migrated databases, so production/dev DBs that have operation_xdr as TEXT will keep that type and will likely break once the app starts inserting BYTEA. Add a new forward migration that ALTER TABLE operations ALTER COLUMN operation_xdr TYPE BYTEA USING decode(operation_xdr, 'base64') (or equivalent), and avoid rewriting already-shipped migrations.
