Hi

Quick question.  I have a 2 node cluster - each node has its own ip.

But from reading this, I really need a 3rd ip, which potentially floats between the nodes to which ever is the master / rw node.

Is that right? Sort of makes sense I guess

I would suggest you repmgr, with this tool you can do "repmgr standby switchover" to perform such tasks.
