However, we've discovered an existing file-based database ({{ matrix_postgres_db_migration_request.engine_old }}) in {{ matrix_postgres_db_migration_request.src }}. It appears that you've been using this bridge with a file-based database engine until now. To continue using {{ matrix_postgres_db_migration_request.engine_old }}, opt into it explicitly: add `{{ matrix_postgres_db_migration_request.engine_variable_name }}: {{ matrix_postgres_db_migration_request.engine_old }}` to your vars.yml file and re-run this same command. We'd normally auto-migrate you to Postgres, but we can't do it on the {{ matrix_architecture }} architecture. Our pgloader container image only supports amd64 (for now).
