This bug concerns sub-SELECTs that reference variables coming from the

nullable side of an outer join of the surrounding query.

In 9.1, queries affected by this bug would fail with <quote>ERROR:

|
||||||
|
8.4, you'd silently get possibly-wrong answers, since the value

transmitted into the subquery wouldn't go to null when it should.
