When translating the DXL dispatch values, the target content IDs should be unioned and deduplicated rather than requiring every constant to hash to one segment. The regression matrix should include values on one, several, and all segments, duplicate constants, explicit `OR`, `IN`, and a null-containing predicate, then compare ORCA with the Postgres planner's dispatch set. It is also worth preserving the all-segments fallback for non-constant or parameterized values whose segment cannot be known safely at plan time. -- This is an automated message from the Apache Git Service.
