Thanks for that explanation, now I understand the problem.

I don't really think this would be required to bump Postgres its
minimum supported postgres version. psycopg is a client and postgresql
is the server, it seems fine for them to use different Python
versions. The postgresql-server package could depend on python3.9,
while psycopg packages would happily use python3.6.
