The encoding of user & database names was my main concern. If they can
only be 7-bit ASCII in practice, that's easy..

Are the strings in the ParameterStatus encoded with the old or new
client_encoding? I need to know the point in the stream to switch
encodings. I suppose this is only an issue if there are pairs of
encodings where "client_encoding" or the encoding names encode
differently in the two encodings. Is it safe to assume that 7-bit ASCII
is always encoded unchanged regardless of the encoding in use?
