pg_dump is only guaranteed to work correctly in the server encoding.
If you force it to use a client_encoding different from the server's,
it might or might not work, for reasons far beyond that one --- the
big problem usually is data containing characters that have no
equivalent in the client encoding. So I'm not particularly excited
about whether fmtId is multibyte safe within pg_dump. If we were to try
to use it in more general contexts, it would probably need more work.
