> Outer joins, especially full outer joins or outer join with filter on 'ON clause' is
not showing proper results. For example, query in test join_1to1.q
> {code}
> SELECT * FROM join_1to1_1 a full outer join join_1to1_2 b on a.key1 = b.key1 and a.value
= 66 and b.value = 66 ORDER BY a.key1 ASC, a.key2 ASC, a.value ASC, b.key1 ASC, b.key2 ASC,
b.value ASC;
