What that means is "we don't implement this, but it's required by POSIX, so we really ought to get around to it someday". I have considered the idea of deleting mention of multi-character collating elements from the preceding paragraph, but then we'd be left with nothing but a statement that "[.x.]" means the same thing as "x" inside a bracket expression. Which is weird and confusing enough that we'd still have to talk about multi-character collating elements in order to explain why it's like that. > Furthermore, it appears that this disclaimer has been part of the docs since > at least version 10, so it's not even clear that this feature is even > currently being seriously considered for implementation. Hah! Look a bit further back :-( regards, tom lane
