Well, under this point of view I feel a bit lucky now. Having built-in streaming replication is a big advantage and gives me the chance to avoid third party applications. Despite there are good solutions out there I believe that less complexity is always better. Plus, I would really like to avoid a

After some enlightening considerations by Scott Marlowe I'm actually now considering a streaming replication with dedicated network connection and two different data dirs on the same storage. This would bypass the lock issue, make replication very fast and make my life "easier" with one reliable (r

Hi everybody, I'm trying to figure out a way to setup a PostgreSQL HA cluster solution. For the record: - I've already tried pgpool-II 2.x in Synchronous Multi Master Replication mode and I was satisfied by it's functionality but concerned about having the same data growing on several nodes - I've
