Bug with plpgsql function after drop column ?

Hi
I just encountered a reproducable bug with plpgsql function "return
next" after drop column:


create table test (
    id int not null primary key
);

insert into test values (1);

create or replace function get_test(int)
returns setof test
as 'declare
    rec record;
begin
    for rec in select * from test where id=$1 loop
      return next rec;
     end loop;
    return;
end;'
Language 'plpgsql';

select * from get_test(1);

alter table test add name text;


select * from get_test(1);

/*
FEHLER:  wrong record type supplied in RETURN NEXT
KONTEXT:  PL/pgSQL function "get_test" line 5 at return next

works after recreate of function
*/


alter table test drop column name;
select * from get_test(1);

/*
FEHLER:  wrong record type supplied in RETURN NEXT
KONTEXT:  PL/pgSQL function "get_test" line 5 at return next

DOES NOT works after recreate of function!!!!!!


PostgreSQL 8.1.3

Workaround is to drop/recreate the table or (what was easier in our
case) dump/restore database. Is it a known known?
