But now, my dude is about pgpool. Do you think It can work well just as a balancer in this environment?
I cannot tell you that with any confidence without knowing more about the application than is going to be practical. The best I can do is "probably, with the caveats already explained re async multi-master above".
My main troubles from the beginning have been in recovery and I dind´t find detailed doc in that way. Most of times, I need to delete data directory in node 2 and starts init replication again.
