I wouldn't hold your breath waiting for that to change.

A possible workaround is to run the postmaster with lc_messages=C and
then switch to your desired message language per-session.  It would
certainly work to send lc_messages along with client_encoding in the
startup packet; or possibly you could set those settings as per-database
or per-role settings to avoid needing to teach the application code
about it.  This would mean that bad-password and similar errors would
come out in English, but at least they'd be validly encoded ...
