Allowing dash character in LTREE
It could be useful to allow the `-` char in allowed LTREE label
characters (currently
a-zA-Z0-9_ https://www.postgresql.org/docs/9.6/static/ltree.html)
The reason is to allow to use more easily base64 ids, (like
https://github.com/dylang/shortid, ...), uuid's too in labels
`-` is also not used as a query operator as a plus

This is the third time you've posted this suggestion. Its been seen by
the people you are sending it to.
I don't follow how this helps for UUID - they are not usually generated
hierarchically...
I'll +1 the thought, but I won't be providing a patch.

Ah sorry, first time, I thought it didn't pass
It's to support multiple ids (base64 ones are frequent) (or uuid's) in a
path. I think it's more practical than an array, for searching and sorting
But I understand that LTREE's main purpose is probably more for words
'breadcrumbs' etc..

There is a patched version here
https://github.com/adjust/ltree
Which allows almost any char but uses '::' as label separator my it's an inspiration to do your own patch.

interesting, but I like '.' as path separator, it's url-friendly, and easy
I used some simple `path TEXT CHECK (path ~ '^[\w.-]+$')` but now I
regret it, because it's not as easy to index and optimize requests
