Postgres streaming replication to a different schema on another server?
Streaming replication can't do this - it can only replicate the whole database cluster together, as a unit.

I think you want Londiste, Bucardo, or maybe even Slony-I for this. I've used Londiste for similar jobs and it works well.

There's also ongoing work on an in-core feature that meets this need, logical replication / bidirectional replication. It's pre-alpha quality, though, so I suggest waiting until it appears, hopefully in PostgreSQL 9.5. Parts of it have been included in 9.4, so some 3rd party tools may be able to use it down the track.
