I think you think that because you misunderstood what I said in [1].
I'll rephrase it for you:

Because people promote the .0 as not yet production-ready, it means
that fewer people bother testing with beta and RC versions. Lack of
beta testing is what causes .0 to contain more bugs than it otherwise
might, so my suggestion is that we should be encouraging people to run
beta and RC in their test environments to try to increase the
stability of .0 versions.

I struggle to imagine anyone with any respect for the PostgreSQL
project disagreeing with that, so I suspect you and Johnson must have
misunderstood.

Also, I was highlighting that I agreed with the paradox pointed out by Ron.

Clear?

You should pay more attention to the quotes above my reply. I don't
see any of my replies quoting anything about upgrading a production
database to 18.0.
