You never need to group by a constant, so this would work fine (and be
compliant with the standard, which your given example is not):

SELECT f1,f2,count(f3) as countOff3, sum(f4) as countoff4,f5,"-" as f6
FROM mytable
GROUP BY f1,f2,f5

Depending on what's happening upstream, it might also help to explicitly
cast the "-" to some specific datatype, eg

    select ..., "-"::varchar as f6 ...
