Thread: FOR i IN REVERSE documentation error?

In the 7.2 documentation, Section 23.2.6.2, at
http://postgresql.crimelabs.net/devel-corner/docs/postgres/plpgsql-description.html

it shows the example:

  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
     -- some expressions here
  END LOOP;

which does work (10 iterations).

Note:  This error is also in the 7.1 documentation.  I tested
it in 7.1 but not 7.2.

Thank you,
Norm Megill

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';
