Agreed. I was thinking currently for logical replication both walsender and slot are database-specific. So we need a way to distinguish the WAL for global objects and then avoid filtering based on the slot's database during decoding. I also thought about whether we want to have a WALSender that is not connected to a database for the replication of global objects but I couldn't come up with a reason for doing so. Do you have any thoughts on this matter? -- With Regards, Amit Kapila.
