I'd like to get failover slots in place for 9.6 since the're fairly self-contained and meet an immediate need: allowing replication using slots (physical or logical) to follow a failover event.

I'm a bit confused about this now.

We seem to have timeline following, yet no failover slot. How do we now follow a failover event?

There are many and varied users of logical decoding now and a fix is critically important for 9.6.

Do all decoding plugins need to write their own support code??

Please explain how we cope without this, so if a problem remains we can fix by the freeze.
