@tswast I don't understand the test_reflect_select failure on 3.9. It seems flaky, mabye?

google.api_core.exceptions.BadRequest: 400 Duplicate column names in the result are not supported when a destination table is present. Found duplicate(s): record, name, age

@jimfulton was hitting that too. The error message isn't right, since we aren't specifying a destination table. I think it is some flakiness in the backend. Since we have a job ID, I went ahead and filed internal issue 196630638 so that the backend folks can investigate.
