Aleksey, a suggestion: The vast majority of the postgresql wire
protocol compresses well. If your WAN link is not already compressed,
construct a compressed SSH tunnel for the postgresql TCP port in the
WAN link. I've done this when rebuilding a 300GB database (via slony)
over a bandwidth-limited (2MB/s) VPN link and it cut the replication
resync time down significantly.
