EXISTS operator returns NULL when multiple predicates are present

[majetideepak]

What happens?

EXISTS operator returns NULL. The documentation says it should only return true or false.

To Reproduce

create table u(u0 int, u1 int);
create table t(t0 int, t1 int);
insert into u values(1, 10);
insert into t values(1, 11);
insert into u values(null, 20);
insert into t values(null, 21);
SELECT t0, t1, EXISTS (SELECT * FROM u WHERE u0 = t0 AND u1 < t1) FROM t;
