Hmm ... as I was reading through the email thread, I saw a suggestion
was once made to look at ltree, and then I noticed the patch as presented
had simply gone with regular expressions instead. I wonder if there'd be
a way to work it so an operator can be specified, and allow you to treat
the names as (say) ltree labels if that suited your application.
