I've looked at the v22 patch set, and here are some comments:
0001:
Do we need regression tests to make sure that the slot's
confirmed_flush_lsn matches the LSN of the latest shutdown_checkpoint
record?
0002:
+ <step>
+ <title>Prepare for publisher upgrades</title>
+
Should this step be done before "8. Stop both servers" as it might
require to disable subscriptions and to drop 'lost' replication slots?
Why is there no explanation about the slots' confirmed_flush_lsn check
as prerequisites?
