The driver does not rewrite queries.    This would be the wisdom of the MS
Jet Engine.  My guess is, that the backend should handle this statement:

    daveh=> (select 1) union all (select 2);
    ERROR:  parser: parse error at or near "("

In the meantime, can you construct this as a pass-through query?
