Coding when open conection

Hi all,

I'm new in this list. My name is Oswaldo and my english is bad (sorry).

I have a problem when I try to connect with a bad user or a bad database name:

Server:
Postgres 8.1 windowsXP
Database encoding: UTF8
postgres.conf
    client_encoding UTF8
    lc_messages es_ES

Client:
Python 2.4.2 + psycopg2 2.0b8
defaultecoding UTF8
Windows XP

The Conection:

import psycopg2 as pg
import psycopg2.extras as pgxtra
....
pgcon = pg.connect(" ..... ")
pgcon.set_client_encoding('UTF8')


When I connect with a valid user and database there is no problem with spanish 
chars and simbols.

But if I put a bad user in the connection string I have the following message:

  File "C:\Python24\lib\encodings\utf_8.py", line 16, in decode
    return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xab in position 96: 
unexpected code byte

These exception is caused by the Postgres spanish error message:
        FATAL:  no existe el rol «user»

where 'user' is eclosed between '«' and '»' chars.

I try to connect with a bad user with PgAdminIII and EMS and both show the 
message correctly.
Hereby I suppose that the problem is that psycopg2 don't use utt8 until set_client_encoding is 
sended, and the message is received before it.

Thanks.
