andrew, I appriciate pg and it's free open source features - maybe I've
chosen a wrong formulation.

Hi,
I have to build a load balanced pg-cluster and I wanted to ask you, if this
configuration would work:
A drbd disk in dual primary mode with ocfs2-filesystem.
Will there be any conflicts if using the shared volume as PGDATA directory?
R+W is a required feature for this cluster.
Thank you

Thank you for your detailed information about HA and LB. First of all it's a
pitty that there is no built-in feature for LB+HA (both of them,
simultaneous).
In my eyes, the pgpool2/3-solution has to much disadvantages and
restrictions.
My idea was the one, that john described: DML and DDL are done

Oracle RAC works by having a distributed cache and locking manager
