We're moving to Postgres 9.2 on RHEL 7 and as part of this we are going to
setup a slave database as our data warehouse. We would like to use the
streaming replication that's built into 9.2, so we would want to remove all
of the data from an old partition on the master but have it stay on the
slave. I was reading the documentation [1] and it sound like this is not
possible.
Is there a way to make this sort of setup work with the streaming
replication that's built into Postgres 9.2?
Thanks,
Dave

Dave,
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.
regards,
Feike

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?
Thanks,

Slony would be my choice because I know it pretty well. The same cannot be
said of bucardo.

I know Slony does, but I don't have any recommendation for one or the other.

Hi Dave,
I don't know if DRBD will help to fulfil your requirement.
But DRBD is a nice one to try since it will replicate a whole
disk/volume from 1 server to backup server.
Therefore, you'll need a dedicated disk/volume for your PostgreSQL
data directory to be replicated to the same size of disk/volume in the
backup server.
