Consider the following test case:

CREATE VIRTUAL TABLE rt0 USING rtree(c0, c1, c2);
INSERT INTO rt0(c2) VALUES(NULL);
SELECT * FROM rt0 WHERE rt0.c2 >= 'a'; -- unexpected: fetches row

Unexpectedly, the inserted row is fetched, even though the predicate should evaluate to FALSE:

SELECT rt0.c2 >= 'a' FROM rt0; -- 0
