Steven Hawkins resolved TEIID-5434.
-----------------------------------
    Fix Version/s: 11.0.2
                   11.1
                   10.3.4
       Resolution: Done


The placement of the select node is due fairly specific circumstances - in this case a union where a branch has a window function.  In most instances the select node would be pushed under the source node.  Addressed by updating the output columns of any intervening nodes.
