   > If the fix is to resolve the nodes, then this should be fine. If the fix 
were to change how v2 works and avoid some call to get the schema of a plan, 
then I would be concerned.
   
   This patch is to resolve the nodes prior to get a schema (via having 
temporary plan), while it doesn't touch the actual plan so that it would work 
as before.
   
   I agree DSv2 is a moving target, but the bug is affecting not only for 
master branch but also for 2.4/2.3 as well. So I hope we get it resolved first, 
and fix it (again) when new DSv2 is concerning.
