Hello
I found a plpgsql bug:

create or replace function fx()
returns void as $$
declare a int; b int;
begin
Â* select 10,20 into a;
end;
$$ language plpgsql;

this is bug, or minimally potential source of strange behave.

AFAICS this is intentional --- see the comment in exec_move_row.

In any case, I think tightening it up is more likely to break working
applications than do anything helpful.

I agree with you about break working application

But this is good
example what should be checked in CHECK statement.

but it should be bug - it has no sense - no in this form - it is
assign row to scalar.

I found a some mysterious and very difficult identified bugs in one
application based on this behave.

Regards

Pavel
