Log message:
    Another round of protocol changes.  Backend-to-frontend messages now all
    have length words.  COPY OUT reimplemented per new protocol: it doesn't
    need \. anymore, thank goodness.  COPY BINARY to/from frontend works,
    at least as far as the backend is concerned --- libpq's PQgetline API
    is not up to snuff, and will have to be replaced with something that is
    null-safe.  libpq uses message length words for performance improvement
    (no cycles wasted rescanning long messages), but not yet for error
    recovery.
