My original code depends on summing a column that should be 0 if the values are null. For some reason all values were 1, indicating a row was always joinable. It seems the above query has a problem with the constant, which in my own code was a true or 1.
Reproducible: Always

Build Identifier:
create table a (a integer);
create table b (a integer);
insert into a values (1);
select * from a left join (select a, 20 from b) as x using (a);
I expect:
1, NULL
In MonetDB I get:
+------+------+
| a | L2 |
+======+======+
| 1 | 20 |
+------+------+
1 tuple (4.655ms)
In PostgreSQL I get:
a | ?column?
---+----------
1 |
(1 row)

we pushed up the project with the constant through a left join. This is not correct. ie fixed.
