I think you need to address the items mentioned in this blog, and the
email link it mentions:
https://momjian.us/main/blogs/pgblog/2020.html#July_1_2020
I am not clear this is a feature we will want. Yes, people ask for it,
but if the experience will be bad for them and they will regret using
it, I am not sure we want it. Of course, if you code it up and we get
a good user experience, we would want it --- I am just saying it is not
clear right now.
