This is complex because we need to exclude the partitions specified. (b) The other complexity is combining Except list containing partitions and other publications specifying partitions or partitioned tables both during replication and probably during initial sync. I think it will be better if for the first version, we allow only root partitioned table to be specified in the Except Table list. This would mean that if the user tries to attach that root partition table to another root then we should give an error. If we go via this route, it will be important to allow users to remove some tables from the Except list, so we can provide Alter Publication <pub_name> Set Except Table (table_names). I think excluding specific partitions may also have some use cases but adding additional complexity and maintenance effort is worth, if there is a real field demand for such a feature. Thoughts? -- With Regards, Amit Kapila.
