He said something about losing any data due to the loss of the master being unacceptable, so synchronous was the only way to go. But if the machines are separated by any real distance, the speed / latency of the link will be the deciding factor in the write performance of the whole system. I think they might be better off having a local synchronous clustering solution (i.e. two machines running in failover on shared storage or something) and then async rep cross country if there's any distance to the other server. What to do about slony not handling LOBs I don't know. ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
