In the following SQL command sequence, query 3 returns no results when it should return "1":

CREATE TABLE t1(v text);
INSERT INTO t1 VALUES('1'),('2');
SELECT 1, v FROM t1 WHERE v=1;
SELECT 2, v FROM t1 WHERE v='1';
SELECT 3, v FROM t1 WHERE v IN (1);
SELECT 4, v FROM t1 WHERE v IN ('1');
SELECT 5, v FROM t1 WHERE v IN (1,2);
SELECT 6, v FROM t1 WHERE v IN ('1','2');
