I wanted to discuss 0003 patch about cascading standby's. It is not clear to me whether we want to allow physical standbys to further wait for cascading standby to sync their slots. If we allow such a feature one may expect even primary to wait for all the cascading standby's because otherwise still logical subscriber can be ahead of one of the cascading standby. I feel even if we want to allow such a behaviour we can do it later once the main feature is committed. I think it would be good to just allow logical walsenders on primary to wait for physical standbys represented by GUC 'standby_slot_names'. If we agree on that then it would be good to prohibit setting this GUC on standby or at least it should be a no-op even if this GUC should be set on physical standby. Thoughts? -- With Regards, Amit Kapila.
