PL/Ruby, INOUT parameters / SETOF record

["Philippe Lang" <philippe.lang@xxxxxxxxxxxxxx>]

Hi,

I am testing PL/Perl under Postgresql 8.1.3, and I habe the following test
procedure:

--------------

CREATE FUNCTION perl_test(a inout integer, b inout integer, r1 out integer,
r2 out integer) SETOF record AS 
'
    my ($a, $b) = @_;

    $r1 = $a + $b;
    $r2 = $a * $b;

    return_next {a => $a, b => $b, r1 => $r1, r2 => $r2};
    return_next {a => $b, b => $a, r1 => $r1, r2 => $r2};

    return undef;

' LANGUAGE plperl;

--------------


How would you translate that in PL/Ruby?

I have a link to http://moulon.inra.fr/ruby/plruby.html, which is apprently
the only documentation, and I find it quite hard to do the translation.

Thanks!
