In 6.5.3, it seems that UNION is not allowed inside a sub-select:
bray=> select p.id, p.name, a.town from person* as p, address as a
bray=> where p.id in
bray-> (select id from customer union select id from supplier);
ERROR: parser: parse error at or near "union"
The same applies to EXCEPT and INTERSECT.
Is this a permanent feature, an oversight, or something already on the TODO
list?
