PFC,
Correct. I use a pyro-remote server.

What about a SSH tunnel using data compression ?
Setup on multiple Windows Workstations in multiple Installations is not possible.
If you fetch all rows from a query in one go, would it be fast ?
I tried the same copy_to via VPN. It took 10-50x the time it took locally.
Also, PG can now COPY from a query, so you don't really need the temp
table... I know, but was stuck to 8.1 on some servers.
