Hi Peter, Thanks for answer. Just to clarify, they are disabled during initial sync only or are always disabled on subscriber side? Are all triggers disabled during initial sync or just foreign keys? How can I know that initial sync completed for all tables? Is it checking when pg_subscription_rel.srsubstate is 'i' or 'd' for all tables or there is a better way?
