| I've been playing around with streaming replication, and discovered that the following series of steps *appears* to work without complaint: - Start with master on server A, slave on server B, replicating via streaming replication with replication slots. - Shut down master on A - Promote slave on B to master - Create recovery.conf on A pointing to B - Start (as slave) on A, streaming from B After those steps, A comes up as a streaming replica of B, and works as expected. In my testing I can go back and forth between the two servers all day using the above steps. My understanding from my initial research, however, is that this shouldn't be possible - I should need to perform a new basebackup from B to A after promoting B to master before I can restart A as a slave. Is the observed behavior then just a "lucky fluke" that I shouldn't rely on? Or is it expected behavior and my understanding about the need for a new basebackup is simply off? Does the new pg_rewind feature of 9.5 change things? If so, how?
