[legrand legrand]

Hello 
here is an unexpected error found while testing IVM v11 patches

create table b1 (id integer, x numeric(10,3));
create incremental materialized view mv1 
as select id, count(*),sum(x) from b1 group by id;

do $$ 
declare 
        i integer;
begin 
        for i in 1..10000 
        loop 
                insert into b1 values (1,1); 
        end loop; 
end;
$$
;
