SELECT 1st field

Hi,

I've spend some time checking the documentation but haven't been able to
find what I'm looking for.
I've got a function that returns a set of integers and a view that
selects from the function.
What I need is the ability to name the column in the view, ie.

create function func(i int) returns setof integer as $$
...
...code
...
$$ language plpythonu volatile;

create view v as select 1 as "id" from func(5);


In other words I'd like to refer to the first (and only) field returned
and give that an alias, in this case "id".

In some SQL dialects you can use "select 1" to select the first field,
"select 2" to select the 2nd field and so on.

Any suggestions?

regards,
Jan
