Yeah, current Postgres multi-master projects seem to be focusing on
shared-nothing architecture as opposed to a shared-disk one. I guess the
advantage of the former is that specialized (i.e expensive) hardware is
not required to attempt to overcome the point of failure with
shared-disk systems - the disk they share.
