create table foo (f1 int, f2 text);

insert into foo values(1,'a');
insert into foo values(2,'b');
insert into foo values(3,'c');

create or replace function get_foo(int) returns foo as 'select * from 
foo where f1 = $1' language 'sql';

create or replace function use_foo(foo) returns text as '
declare
  v_foo alias for $1;
begin
   return v_foo.f2;
end;
' language 'plpgsql';

regression=# select use_foo(get_foo(2));
  use_foo
---------
  b
(1 row)

HTH,
