Обсуждение: Vacuum from within a function crashes backend

Hello,

I did a vacuum from within a function, and it went sig11 on me.
Is it illegal to do that?

The function:

drop function xorder1_cleanup();
create function xorder1_cleanup() RETURNS integer AS '
declarex record;c integer;
begin  c:=0;  FOR x IN SELECT order_id,count(*) as cnt FROM xorder1_updates group by order_id LOOP    if x.cnt > 1 then
    c:=c+x.cnt;         delete from xorder1_updates where order_id = x.order_id;      insert into
xorder1_updates(order_id)values (x.order_id);    end if;  END LOOP;  execute ''vacuum full analyse xorder1_updates;'';
returnc; 
end;
' LANGUAGE 'plpgsql';

Huh...  what version is this?  In current sources, VACUUM cannot be run
inside a function (it will throw an ERROR).  In 7.2[.1] I see there is
no protection against this.

Maybe the fix for this should be backported to 7.2 also.
