PostgreSQL Cluster with shared SAN Database

Hello,

is it possible to creata a PostgreSQL cluster using 2 servers (nodes) which share one database which is located on an SAN?

(like Oracle RAC)

I would like to increase performance, an scalability. So i´d like to run the nodes in active/active mode. I do not want to replicate my data base. The cluster should not be a pure failover or HA cluster. I want both nodes to work on the database on the same time. And if one of the nodes fails, the other node should takeover all operations. But i do not want an active/passive cluster.

If this is not possible with PostgreSQL, which open source database can i use?

Thank you.

FWIW, every PostgreSQL cluster is a collection of backend processes
which share one database at the storage level.
