Correct. I use a pyro-remote server. On request this remote server copies
the relevant rows into a temporary table, uses a copy_to Call to push them
into a StringIO-Objekt (that's Pythons version of "In Memory File"),
serializes that StringIO-Objekt, does a bz2-compression and transfers the
whole block via VPN.

I read on in this thread, and I scheduled to check on psycopg2 and what it
is doing with cursors.
