Re: Backup messages displayed with wrong encoding

Hi,

I would like to clarify the issue with the encoding.

Now that we've got postgres localized (with russian messages), I can see
that the encoding of the pg_dump output not changed depending on the
database setting or the pg_dump option.
It seems that pg_dump changes only the encoding of a database objects
names (see the screenshot).
So it looks like a pg_dump bug, not a feature.
Thanks for your feedback.

Best regards,
Alexander
