------------------------------------

Any idea why this test passed before?

> A SqlTransform may contain a GroupByKey in the global window, this prevents setting windows afterwards. The PubSubTableProvider tries anyway.
> This was exposed by a INSERT INTO pubsub VALUES (1), (2), which implicitly becomes INSERT INTO pubsub SELECT 1 UNION SELECT 2. This then becomes a GroupByKey union.
> For now I'm going to simplify the test.
