hi
in this case you have to use execute:
>> select $1,count(*) from $2 group by $1 order by $1;
execute into myResultSet 'select ' || $1 || ' from ' || $2 || ' group by ' ||
$1 || ' order by ' || $2;
see plpgsql docs for detailed information

Please correct me if I am wrong, but as the last few lines of the first
section in the given document says, you can use $n only for values and not
for identifiers.

And one more thing, may be you would want to use a user-defined return type
