These patches have been split off the now deprecated monolithic "Delegating superuser tasks to new security roles" thread at [1].
The purpose of these patches is to allow non-superuser subscription owners without risk of them overwriting tables they lack privilege to write directly. This both allows subscriptions to be managed by non-superusers, and protects servers with subscriptions from malicious activity on the publisher side.
