IIUC, primary use of pg_subscriber utility is to start a logical subscription from a physical base backup (to reduce initial sync time) as against logical backup taken while creating a subscription. Hence I am expecting that apart from this difference, the resultant logical replica should look similar to the logical replica setup using a logical subscription sync. Hence we should not leave any replication objects around. UDFs (views, and other objects) may have some use on a logical replica. We may replicate changes to UDF once DDL replication is supported. But what good is having the same publications as primary also on logical replica? -- Best Wishes, Ashutosh Bapat
