- Test hashing of an array of a non-hashable element type. - Test UNION [DISTINCT] with hash- and sort-based plans. (Previously, only INTERSECT and EXCEPT where tested there.) - Test UNION [DISTINCT] with a non-hashable column type. This currently reverts to a sort-based plan even if enable_hashagg is on. - Test UNION/INTERSECT/EXCEPT hash- and sort-based plans with arrays as column types. Also test an array with a non-hashable element type. - Test UNION/INTERSECT/EXCEPT similarly with row types as column types. Currently, this uses only sort-based plans because there is no hashing support for row types. - Add a test case that shows that recursive queries using UNION [DISTINCT] require hashable column types. - Add a currently failing test that uses UNION DISTINCT in a cycle-detection use case using row types as column types.
