Consider the following test case:
<pre>
CREATE TABLE t0 (c0);
INSERT INTO t0(c0) VALUES ('a');
SELECT * FROM t0 WHERE LIKELY(t0.rowid) <= '0'; -- unexpected: row is not fetched
</pre>
Unexpectedly, no row is fetched. The expression LIKELY(t0.rowid) <= '0' should evaluate to TRUE:
<pre>
SELECT LIKELY(t0.rowid) <= '0' FROM t0; -- 1
</pre>
