I suspect the central question you have to answer is, "What do you mean by 'improve'?" Do you want to increase the ability to retrieve data? Decrease the potential for data loss? Shorten the recovery time to read/write availability? And so on. The answers for these different questions will determine which trade-off you need to make. And rest assured, there is abolutely no solution in the world -- not even a really expensive commercial one -- that requires no trades. Distributing data reliably with ACID semantics and no data loss or corruption or loss in write throughput is not possible, at least today. You have to pick which poison you want :) A -- Andrew Sullivan ajs@xxxxxxxxxxxxxxx -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
