There are also some improvements needed to the user interface - in particular, providing a function interface for changing replication set memberships for connections so there's no need to manually restart the apply backends after a change, and providing default replication sets for a node. Current development priorities mean that these aren't expected in the next few releases.
Note that selective replication affects *only* replication of rows. DDL is still replicated on tables that are not members of any active replication set. Also, changing replication set memberships won't synchronise the added table's rows from other nodes, it'll just start replicating new changes from its current state. You generally want to set up replication sets before starting to add data to tables.
All this applies to 0.9.0 and is, of course, subject to change in future releases, time and resources permitting.
