Grega,
Well, as I said, that's why I was asking - I'm willing to give it a go
if nobody can prove me wrong. :)
Why not? If you have time?
I thought you knew - OCFS, OCFS-Tools and OCFSv2 have not only been open-

smarter than all those kernel hackers doing this for a living? I doubt it.
Grega,
Furthermore, this filesystem would be a blazing one stop solution for
all replication issues PostgreSQL currently suffers from, as its main
design goal was to present a consistent file system image across the
servers in a cluster.
Does it work, though? Without Oracle admin tools?

Hello Jaime,
I think you're on the right track but have gotten some

As I remember, the original email asked if Postgres
