OK, the first thing to note is that there is an easy workaround,
which is to use a sort routine that doesn't need $a/$b. Example:
create or replace function mysort() returns text language plperl
as $f$
my $sfunc = sub ($$) { $_[0] <=> $_[1] };
my @vals = (5,3,4,2,7);
return join(' ',sort $sfunc @vals);
$f$;
Andrew for the win!
Thanks a lot!
I agree, a documentation note would be fine for this rather doing all
sorts of complicated perl trickery.
