The built-in streaming replication of 9.2 gives you everything, you cannot cherrypick which tables will be replicated and which one will not be replicated.
Basically: The streaming replica will be an exact copy of you primary cluster.
So the answer to your question is no, it's not possible with the streaming replication in 9.2.
Does 9.3 or 9.4 support this sort of configuration? If not, from the table in the documentation, it looks like Slony [1] and Bucardo [2] would both work, so does any one have any recommendations?
