Hello, My understanding is that WAL archiving can not be enabled on the slave in a streaming replication pair.
If this is correct, is there a reason behind it? I can see logs showing up in pg_xlog, so could they not be archived? The reason I ask is if this happened it would allow the following with a streaming replication pair (A,B): 1. Start A as master 2. Attach B as slave using basebackup 3. work .... 4. Promote B to master 5. Restore A from a scheduled backup to a time before promotion 6. Attach A as slave pointing at B's WAL archive If we used A's WAL archive in this case and A had writes after the promotion then we would get timeline errors. As far as I can tell, using the WAL archive from B would resolve this issue. Or have I missed something here?
