This issue happen even ALTER SUBSCRIPTION. I guess the main cause is that acl_kind of pg_publication and pg_subscription of ObjectProperty array are not correct. These values should be set ACL_KIND_PUBLICATION and ACL_KIND_SUBSCRIPTION instead of -1. Attached small patch fixes this issue and adds regression test.
