Re: encoding of PostgreSQL messages

Hi,

This topic seems to be related to the bug report
    [ODBC] Localized error messages, wrong charset
.

It it true ?
IIRC the backend knows nothing about the server encoding in
authentication phase.

Psqlodbc Unicode driver sends connection startup message which
contains the client_encoding(=UTF8) guc parameter. Attached is
  a trial patch so that the psqlodbc Unicode driver can get
properly localized password error messages.
