Problems with stored procedure (function)

Hello pgsql-novice,

I'm trying to return a set of rows from a stored procedure, but
haven't quite hit on the right syntax. I'm sure this is quite a
trivial question, but all my googling has failed me (and so has
"PostgreSQL: The comprehensive guide to building, programming, and
administering PostgreSQL databases, Second Edition").

My code is:

create table country (
   name varchar(100),
   alpha_two_code char(2),
   alpha_three_code char(3),
   numeric_code int,
   primary key (numeric_code)

create or replace function load_country() returns setof country as
   return query select * from country;
language 'plpgsql';

The problem I have is my function keeps on returning a single column
with the name of the function, rather than something akin to the table
I've defined:

sanzala=# insert into country values('a','b','c',123);

sanzala=# select * from country;
 name | alpha_two_code | alpha_three_code | numeric_code
 a    | b              | c                |          123
(1 row)

sanzala=# select load_country();
 (a,"b ","c  ",123)
(1 row)

I guess the fault is in "setof country", but I've tried returning
_country, country%rowtype, etc - all with no luck. What am I doing

Many thanks for your time,
