setof (more than one column)

Hi,

I am doing some tests with functions in 7.2b4. I got some stuff to work 
that returns 'setof text' but I was wondering whether it is possble to let 
the function return more than one column, something like:

create function myfunc (integer) returns setof (text, integer)

or

create function myfunc (integer) returns setof text, integer

I've searched the docs about the syntaxt of the 'setof' keyword but could 
not find really much.

TIA,
