Thanks you for yours post.
I am reading your link suggestions of the PostgreSQL. It's helped me for
I wanted to build a cluster master-master server, and I found the PGCluster
tools allow for this environment. But more reading of this topic, the
server performance could be worse than a single server.
I need build a load balancing cluster of the database. And for that I
looking for the node master-master server or read/write server.

yes, but now I believe, that's not the best choice for master-master
Changed, now I prefer build a master-hot standby (read/write node-read only
node ) server for the load balancing cluster.
It's possible send request for both nodes for build load balance?

With active/passive HA, I don't offer load balancing.
I see about DRBD three-node setup.
And also I thinking of the NAS shared-disk, but apparently that isn't
compatible with the ocfs, neither with gfs.
Which is the best choice for the shared data between databases server, and
offer load balancing?
I listen of the HAProxy, that offer too load balancing. If I use HAProxy is
equal to use LVS, and so I must choice between both. In this moment I don't
