Are these test failures related to this PR? I’ve also added Trevor as a reviewer since he probably have more context on the background of these changes than I do.

It can also be a single value in SQL. E.g. OBJ.MAKE_REF("gs://something", "us.my_connection"). It can be useful in local experiments. Do we want to support the case?
