Обсуждение: Using 9.3 as a slave to 9.1 for upgrade purposes
As a way of upgrading, I'd like to setup a 9.3 cluster as a slave to a 9.1 master so that I can then promote that 9.3 instance to master, using streaming replication.

Streaming replication has to use the same major PG version. You can do that with Slony. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + Everyone has their own god. +

Not possible with streaming replication. It is a binary format so the version and system architecture have to be the same on both sides of the equation. You would need to use another replication method, say something like Slony.
