I can confirm in testing this function that you are correct. I have
fixed the documentation as you suggested. Thanks.
---------------------------------------------------------------------------
drop function bb();
create function bb () returns integer as 'declare i integer;
begin
for i in reverse 10..1 LOOP
insert into aa values (i);
END LOOP;
return 0;
end'
LANGUAGE 'plpgsql';
> In the 7.2 documentation, Section 23.2.6.2, at

>
> FOR i IN REVERSE 1..10 LOOP
> -- some expressions here
> END LOOP;

> This loop does nothing. I think it should be:

> FOR i IN REVERSE 10..1 LOOP
