I am using pglogical in postgresql11 to replica data from master cluster to a slave cluster. It is working fine. but I run pglogical.drop_subscription to delete the subscription from slave instance. After that I tried to run pglogical.create_subscription to re-create the subscription, but the subscription status is down immediately.
When read the instance log, it has some errors about duplicate key value violates unique constraint "Entity_pkey". I think this error means there are many duplicate primary key data in the slave cluster. It is expected since the subscription worked before which leave many data in the database.
I don't have configuration for the setting pglogical.conflict_resolution which means it should use the default value apply_remote.
How can I re-create them without deleting these data from slave instance?
