Description: Error in some kind of UNION query.
Details:
this query work :
select null UNION 1;
this query doesn't work :
select null UNION null UNION 1;
ERROR: UNION types text and integer cannot be matched
You probably mean
SELECT NULL
UNION
SELECT NULL
UNION
SELECT 1
Proper casting will help, insuring the correct type can be determined
from the first SELECT. Changing the order to have SELECT 1 does the job too.
