andrew, I appriciate pg and it's free open source features - maybe I've
chosen a wrong formulation.
in my eyes such a feature is getting more important nowadays. Postgresql-R

I think it's a pity that I'm not paid a million dollars a year, too,
Thank you for your detailed information about HA and LB. First of all it's a

Hi,
I have to build a load balanced pg-cluster and I wanted to ask you, if this

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
