SETOF is to return more than one record, not more than one field. Also,
SETOF is only currently working for SQL language functions.
What you probably need is following:
create procedure x returns foo ....
and create a table foo with list of fields you want to return.
That will work IFF you are not calling this function directly from the
client, but are accessing it from plpgsql code. If you are accessing it
from a client, it won't work. I don't know what will :)

caneasily deal with multiple columns in server side procedures that contain a SELECT, but I can find nothing about how
todo this in PostGreSQL Documentation or anywhere else.
