I've run replication on that general scale. IMV, when you are using PostgreSQL hot standby and streaming replication you need to decide whether a particular replica is primarily for recovery purposes, in which case you can't run queries which take very long without getting canceled for this reason, or primarily for reporting, in which case long-running queries can finish, but the data in the database may get relatively stale while they run. If you have multiple replicas, you probably want to configure them differently in this regard. -Kevin -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
