Reinterpreting the question and taking the  pseudocode
semi-literally is
the following closer to what was asked?
             ref. 39.2. Structure of PL/pgSQL
             <http://www.postgresql.org/docs/9.2/static/plpgsql-structure.html>

pendari=> CREATE FUNCTION somefunc() RETURNS text AS $$
pendari$>
pendari$> DECLARE
pendari$>   v_some_id int=14;
pendari$> BEGIN
pendari$>   /*
pendari$>     more queries here...
pendari$>   */
pendari$>   RETURN 'this is text'::text;
pendari$> END;
pendari$> $$ LANGUAGE plpgsql;
CREATE FUNCTION
pendari=> select somefunc();
    somefunc
--------------
  this is text
(1 row)

pendari=>
