query block
             :     // it can maintain the uniqueness.  However, since the 
Calcite planner
             :     // uses a single SimplifiedAnalyzer for entire query and 
there are no
             :     // longer separate query blocks (they have already been 
unnested), it needs
             :     // to make the alias globally unique.

> When I run a query like this:
I'm not quite sure what you mean by "text plan" here.  The explain plan?  I did 
see the reference there for the old planner.  The new planner doesn't use 
"explain" yet.  So yeah, I'm not sure what you mean here.
