Amit Kapila 366283961a Allow users to skip logical replication of data having origin. ... This patch adds a new SUBSCRIPTION parameter "origin". It specifies whether the subscription will request the publisher to only send changes that don't have an origin or send changes regardless of origin. Setting it to "none" means that the subscription will request the publisher to only send changes that have no origin associated. Setting it to "any" means that the publisher sends changes regardless of their origin. The default is "any". Usage: CREATE SUBSCRIPTION sub1 CONNECTION 'dbname=postgres port=9999' PUBLICATION pub1 WITH (origin = none); This can be used to avoid loops (infinite replication of the same data) among replication nodes. This feature allows filtering only the replication data originating from WAL but for initial sync (initial copy of table data) we don't have such a facility as we can only distinguish the data based on origin from WAL. As a follow-up patch, we are planning to forbid the initial sync if the origin is specified as none and we notice that the publication tables were also replicated from other publishers to avoid duplicate data or loops. We forbid to allow creating origin with names 'none' and 'any' to avoid confusion with the same name options.
