One of the big new things in Citus 10 is that you can now shard Postgres on a single Citus node. So in addition to using the Citus extension to Postgres to scale out Postgres across a distributed cluster, you can now also:

• Try out Citus on a single node with just a few simple commands
• Shard Postgres on a single Citus node to be “scale-out-ready”
