I can understand that people are worried about not having WAL. But as far as I
remember, I'm afraid those concerns were emotional, not logical, i.e.,
something like "something may happen.". Regarding concrete concerns that
Stephen-san, Magnus-san, Horiguchi-san, Sawada-san and others raised, Osumi-san
addressed them based on their advice and review, both in this thread and other
threads.
I also understand we want to value people's emotion for worry-free PostgreSQL.
At the same time, I'd like the emotion understood that we want Postgres to have
this convenient, easy-to-use feature. MySQL recently introduced this feature.
Why can't Postgres do it?

Other methods are not as easy-to-use, and more complex to implement.
What kind of destiny does this type of feature end up in?
