I take your point about the differences.

In this case, the PostgreSQL project is just about to de-support those
release levels, so that does change things somewhat. I'm not sure why it
would be useful for a future version of Django to advertise support for
a PostgreSQL version that the PostgreSQL project is itself intending to
de-support. That seems likely to cause disappointment, even though you
are correct and it will pass tests.

I am just the messenger in this, carrying goodwill between projects.
