Summary: UNION select returns wrong column type with ADO (VB6)

Initial Comment:
If you do a UNION query like this:

SELECT (name || 'dummy')::varchar AS NewName FROM union_bug UNION
SELECT name AS NewName FROM union_bug ORDER BY newname

you get the data type adLongVarChar in the first field.

Table definition:
CREATE TABLE union_bug
(
  name varchar(15) NOT NULL,
  CONSTRAINT union_bug_pkey PRIMARY KEY (name)
)

In pgAdmin III the data type shown is varchar, so the bug must be in the ODBC driver.
