Hello, I have a pg8.3 server (an 8.4 upgrade is scheduled) on Windows. I would like an other pg server in backup in case of hardware problem on my first server. I use read/write queries and I would like the second pg become master without any human intervention. I saw Slony, but it seems that the backup server is a read-only server which is not good for me. I also saw pgpool. Is it a good solution for me? Does it work alone or with Slony? Is a Windows version exist? Finally, I saw others products like pgcluster or Bucardo, but I don't understand the differences between all those products... Can somebody help me? :) Thanks in advance -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
