Well, if it was *only* a matter of rtl then he could do
ORDER BY reverse(foo)
I don't think we have a string-reversing function (reverse('foo') = 'oof')
at the moment, but one would be easy to write.
But I'm assuming the rtl property is just one of the ways in which
Hebraic sorting differs from plain ASCII... so he really needs a locale.
