* Expand the documentation. Perhaps we could add a step-by-step guide for migrating to SCRAM-SHA-256 since more users will need to do so when MD5 password support is removed. * Remove the hint. It's arguably doing little more than pointing out the obvious, and it doesn't actually tell users where in the documentation to look for this information, anyway.
I think both ideally, but maybe just the hint removal for this patch?
On the other hand, "change your password and update pg_hba.conf" is pretty much all you need, so not sure how detailed we want to get. :)
