Well, this is just another symptom of a lost or uninitialized memory
area; I get
postgres=> select 4 union select 5 union all select null;
?column?
--------
(3 rows)
with apparently blank or null results.
I'll check on the "NULL UNION NULL" problem. Since there is _absolutely
no context_ to assign a type it's a bit strange...
