Hello Dmitry,
Given that it's an open item for PostgreSQL 12,
I'm working on it, but slowly.
I've decided to take a look.
Thanks!
Indeed, looks like 6e5f8d4 introduced a subtle behaviour change, when hostaddr changes are not picked up for subsequent \connect's, and I don't see any mentions of it in the documentation.
ISTM that the documentation is kind of fuzzy enough to match both behaviors.
Although I guess it can be avoided by `-reuse-previous=off`, probably it makese sense to update the docs.
Yep, that is one option. The other is to revert or alter the subtle change, but ISTM that it made sense in some use case, so I wanted some time to think about it and test.
