This is not really a SQL type result; you are probably better of
writing something in a procedural language. That said, something like
this seems to work for 7.2:
create sequence temp_counter; select nextval('temp_counter'), * from whatever;
If you have an 'order by', the above will not work. You could then
try either building a temporary table or using a subselect
select nextval('temp_counter'), * from (select .... order by ...);
