Is there a bug in the logic of inferring output column names? Note how in this example, DF is assigning `y` to the second output column -- pretty randomly! -- instead of using the correct `n_regionkey`. (It is my understanding that in a SELECT with a UNION clause, the output column names are derived from the first SELECT sub-clause; perhaps somebody can dig through the standard to confirm that.) -- This is an automated message from the Apache Git Service.
