Using generate series won't number the rows that way that you would
want. You basically will end up with a cross join between the
generated series and the requested set. There are three ways that I
know of to get a row number:
1) IIRC use a pl-pgsql function that returns an incremented number
2) use SQL by joining using the operator ">=" and Group by aggregate count(*)
3) 8.4 has sum new analytic functions that will do this nicely.
