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?
