Bug reference:      2861

Operating system:   Windows xp sp2 Simplified Chinese Version
Description:        when backup UTF-8 database,pgdump add comments not
encoded in UTF-8
Details:

When I make a backup of a UTF8 database then pg_dump add some comment to
backup file:

-- Started on 2006-12-23 11:04:38 中国标准时间
...
...
-- Completed on 2006-12-23 11:04:40 中国标准时间

'中国标准时间' means in English 'China standard
time'. Unfortunately it is encoded incorretly in GBK, not in UTF-8. It makes
following error during restore:

pg_restore: connecting to database for restore

pg_restore: [archiver (db)] Error while INITIALIZING:

pg_restore: [archiver (db)] could not execute query: ERROR:  invalid byte
sequence for encoding "UTF8": 0xd6d0

You *sure* that pg_dump is 8.2.0?  Because we fixed that before 8.2 rc1 ...

    * src/: backend/utils/error/elog.c,
    bin/pg_dump/pg_backup_archiver.c, bin/pg_dump/pg_dumpall.c:
    Suppress timezone (%Z) part of timestamp display when running on
    Windows, because on that platform strftime produces localized zone
    names in varying encodings.  Even though it's only in a comment,
    this can cause encoding errors when reloading the dump script.    Per
    suggestion from Andreas Seltenreich.  Also, suppress %Z on Windows
    in the %s escape of log_line_prefix ... not sure why this one is
    different from the other two, but it shouldn't be.
