Re: calling procedures is slow and consumes extra much memory againstcalling function

Hi

I try to use procedures in Orafce package, and I did some easy performance tests. I found some hard problems:

1. test case

create or replace procedure p1(inout r int, inout v int) as $$

begin v := random() * r; end

$$ language plpgsql;

This command requires

do $$
declare r int default 100; x int;
begin
  for i in 1..300000 loop
     call p1(r, x);
  end loop;
end;
$$;

about 2.2GB RAM and 10 sec.
