That's how I understood it too. But it will be difficult in our complex storage world to get the storage guys to create
aconsistency group.
Also, what I'm looking for is a plugin that allows to, how Netapp call it, "quiece" the PostgreSQL cluster, i.e. does
start/stopbackup.
I don't really trust the community plugin as it is so old and I'm not sure it gets any more development attention. For
example,what about the API change (exclusive vs. non-exclusive)? Does it use the new API?
Cheers,
Paul
