You are doing something strange. You have what version of postgresql?
If 9.1 or above, then the only correct way to use extension is to say create extension in the desired database. Generally need root privileges database (usually postgres on a linux or pgsql on freebsd)

Blame the locale configuration error OS to the database has nothing to do.
it is necessary to go under postecom in database and create extension ltree ? - vergie.Jerde commented on June 8th 19 at 16:33
