Hi. I found this somewhere:

select a from b order by a using ~<~

I've been searching the docs but I found nothing about this weird ~<~
comparator. Not in comparison operators, String functions and operators,
nor the order by clause. Maybe it has something to do with regular
expressions, but so far I haven't found anything.

Thanks in advance.
