Another round of protocol changes. Backend-to-frontend messages now all · 5ed27e35

由 Tom Lane 提交于 4月 22, 2003

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.
