Please look at a planner error with a virtual generated column triggered
by the following script:
CREATE TABLE t(a int, b int GENERATED ALWAYS AS (a * 1));
SELECT SUM(CASE WHEN t.b = 1 THEN 1 ELSE 1 END) OVER (PARTITION BY t.a)
FROM t AS t1 LEFT JOIN T ON true;
ERROR: XX000: wrong varnullingrels (b) (expected (b 3)) for Var 2/1
LOCATION: search_indexed_tlist_for_var, setrefs.c:2901
(I discovered this anomaly with SQLsmith.)
