Streaming replication and partitions

От

I am basically familiar with postgreSQL (in older incarnations) but have not really done a streaming replication (WAL) setup before.

In planning for my setup, I am going to use table partitioning and tablespaces to keep things as quick as "possible".  However, in a streaming replication environment, will the slave and the master have to be _exactly_ the same in terms of tablespaces?  Is it possible some TBSPACE01 on the master be on /sda1 and the same TBSPACE01 on the slave be on /sdb1?

Will I have to set up identical hardware and identical drives and directory structure between the master and slave?

Thanks.

Yes, as long as sdb1 points to the same directory that sda1 on the other
server points to.

Only in the sense of the database directories, tablespaces are directory
specific.
