question about functions

Hi:

I'm interested in postgres because I want to use transactions
and store procedures (or functions).
I have created this table:
Table1
c1 int4
c2 varchar(5)

And this function

Name: Test
Return: setof int4
Language: sql

"select * from Table1";

But, this is not working because this funcion only return
a set of int4 results... I should replace this to
"select c1 from Table1".

My question is:
How can i return a select with two o more colums?
Like MS Sql server store procedures does.
Is it possible?

Thanks in advance.
Regards
