Hi,

Inspired by following posting, I'm thinking about to use ltree for
full text search purpose.

I noticed that ltree does not allow other than [a-zA-Z0-9] (in C
locale) for a "label". Does anybody know if this is an intended
limitation or not. It seems there's no reason we could allow, for
example, ':' using a backslash or any other escape characters.
