> A correlated grouping expression appears in the pushdown query with the internal group name anon_grpX rather than the proper reference from the outer query.
> For example the user query:
> select x, (select avg\(y) from tbl1 where x = tbl2.x) from tbl2 group by x
> would have
> where x = anon_grp0.x
