Probably a missing language package.

It depends on the perspective. For a system administrator, what you say
makes sense. But from a Postgres user who is expecting consistent
translation, it can be a bit mysterious. And from an engineering
standpoint, translation through strerror() is not tested and -- as far
as I can tell -- only works on glibc.
