Combine query support doesn't repoint nested external references
As I came to discover trying to help someone on the forum the support for correlated subqueries (aka OuterRef
) in combined queries (union
, intersection
, difference
) added in #29338 fails to re-point external references on relabeling (an operation performed on subquery pushdown to prevent table name collisions) causing nested outer query references to be orphaned.
