Query with CASE operator unexpectedly results in "Column must be in the GROUP BY list" error #2813
Description
Consider the following statements:
CREATE TABLE T0(c0 INT);
CREATE TABLE T1(c0 BOOL);
INSERT INTO T0 VALUES (0);
SELECT * FROM T0, T1 WHERE (CASE T1.c0 WHEN T1.c0 THEN T1.c0 END); -- Column "T1.C0" must be in the GROUP BY listUnexpectedly, the query results in an error Column "T1.C0" must be in the GROUP BY list. I found this based on commit 309fe5a.
