Hello Is this restriction only for the subscriber?
If we have not changed the replica identity and there is no primary key, then we forbid update and delete on the publication side (a fairly common usage error at the beginning of using publications). If we have replica identity FULL (the table has such a column), then on the subscription side, update and delete will be performed. But we will not be able to apply them on a subscription. Right? This is an important difference for real use, when the subscriber is not necessarily postgresql - for example, debezium. regards, Sergei
