Durability set What will be behavior of non-transactional DML's

Durability :
transactional DML – supported
non-transactional DML – not supported

This is very inconvenient to customers and confusing.
How we going to handle the use cases or setting. Decision need to be made ASAP.

Example:

\set -durability_level "majority";

insert into default values("k01",{"a":1});

Are we need to raise error due to non-transactional DML. If we ignore user may think we enforcing durability.

Every statement set/unset these parameters is in inconvenient to customers.
