Sorry, I didn't explain well.

I just suggested the order of development. I think paritial recovery
is easier than partition replication because we don't need to think
network nor multiple clients in recovery.

Also, this feature can be developed on the Streming Replication, but
it is under development -- the code is not fixed. So, I'd suggest to
start the development from independent parts from Streaming Replication.

I believe the partial replication will require modules developed
for the partial recovery in the future.
