Since components of a query can run on different storage nodes concurrently, this helps a great deal. It doesn't do the things a column store would help with but it is still a major step forward. As for redundancy, Postgres-XC handles redundancy on the coordinator side, but on the storage node side, I believe you could use streaming replication and other standard PostgreSQL approaches to redundancy there. Hope this helps, Chris Travers
