syncStatefulSetandsyncStreamsboth callcheckAndSetGlobalPostgreSQLConfigurationto compare desired and effective Patroni config. Usually desired is what's specified in the manifest.syncStreamshowever uses the config patch code to create logical replication slots that are not specified in the manifest. These slots then get added to cluster.replicationSlots (only on UPDATE events changing streams). This variable was introduced in #2089 to detect the removal of slots from the manifest. It should only contain slots specified in the manifest.On the next SYNC
syncStatefulSetwill only compare manifest with effective config. The Postgres Operator goes overcluster.replicationSlotswhich now contains slots created for streams, but will not find them in the manifest. Thus, they will be set tonulland get removed.SyncStreams will then recreate them a few seconds later and so on.
