Why is the record not being inserted into the ltree field?

Question

PostgreSQL

If the string is several thousand characters long, it is not inserted into an ltree field, although the formal limit has not yet been reached.
Has anyone come across? Are there any thoughts about this?

Answer 1

I will not duplicate the text from the site, your token must be less than 256 bytes, and the total length is less than 65 kb, while 2kb is advised. I suspect the advice is not in vain.
Speaking more to the point, the question is more about the overall size. Pay attention to the character sizes in utf8 encoding ( https://ru.wikipedia.org/wiki/UTF-8 ).
