If you are ever in LA, you should come to a LAPUG meeting. One of our members also replicates over long distances. He is replicating from California to China using a highly configured slony in combination with other software. His software analyzes the possible routes he has to find the routes with the best latency. He has configures a revolving Master-Slave replication. Perhaps you guys to share notes? -- Regards, Richard Broersma Jr. Visit the Los Angeles PostgreSQL Users Group (LAPUG) http://pugs.postgresql.org/lapug -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
