You've said it's returning "text" whereas it's returning whatever your columns 
are. You'll want to do something like:

CREATE TYPE fn_ret_type AS (
  column1 int4,
  column2 text,
  column3 date,
 ...
);

CREATE FUNCTION function_name(int) RETURNS fn_ret_type ...

If it returns multiple rows you want SETOF fn_ret_type
