I haven’t looked at the patch deeply but regarding 007_sync_rep.pl, the tests seem to fail since the tests rely on the order of the wal sender array on the shared memory. Since a background worker for synchronizing replication slots periodically connects to the walsender on the primary and disconnects, it breaks the assumption of the order. Regarding 010_logical_decoding_timelines.pl, I guess that the patch breaks the test because the background worker for synchronizing slots on the replica periodically advances the replica's slot. I think we need to have a way to disable the slot synchronization or to specify the slot name to sync with the primary. I'm not sure we already discussed this topic but I think we need it at least for testing purposes.
This has been addressed by patch v2 that adds such a setting.
