Not sure if this a function like this does everything you may want, but it may
work for you.
Disclaimer: I have not actually used the proc with the "As" for the column
names,
but I'd expect it "should" work.
CREATE FUNCTION "getlogdata"("int4", "int4", "int4", "int4") RETURNS
"refcursor" AS '
DECLARE curs refcursor;
BEGIN
OPEN curs FOR
SELECT logdata.datavalue As Result1,logdata.timestamp As Result2
from logdata
where logfielddatatype = $1
and graphtargetlog = $2
and (timestamp >= $3 OR $3 = 0)
and (timestamp <= $4 OR $4 = 0)
order by timestamp;
RETURN curs;
END;
' LANGUAGE 'plpgsql';
