   merged to master, thanks!
   
   @LantaoJin can you send a backport to 3.0?

   The patch LGTM. It will be great if you can take a look at 2.4 and see if 
there is an easy fix to make your tests pass. We did a big refactor about CTE 
substitution in 3.0 and I don't know how hard it is to fix the bug in 2.4.

   the patch itself looks fine.
   
   > AnalysisException: cannot resolve 'cte.id' given input columns: [cte.data, 
cte.id];
   
   Do you know why? I expect to see we just ignore the hint, but it reports 
"can't resolve column", which is pretty weird.
