Description: UTF-8 french postmaster messages corrupted
Details:

Hello,

The french messages lost their accents in the latest stable release.
When in 8.0.4 with $LANG=fr_FR.UTF-8, I get:
[postgres(at)bu04 postgres]$ echo $LANG
fr_FR.UTF-8
[postgres(at)bu04 postgres]$ pg_ctl stop
en attente de l'arrt du postmaster....TRACE: arrt en cours des
traces
fait
postmaster arrt

When in 8.0.2, on the same server, with $LANG=fr_FR.UTF-8, I get the
following, which is correct:
[postgres(at)host postgres]$ echo $LANG
fr_FR.UTF-8
[postgres(at)host postgres]$ pg_ctl stop
en attente de l'arrt du postmaster.... fait
postmaster arrt

I did this tests in the same session, I just switch from an environnement to
another by resetting the $PATH and $PGDATA environnement variables.

Thanks in advance.
Thomas
