I agree, but I have no idea how you could do that within the current
pg_hba.conf.
The row is selected by the combination of username/database/ipaddress.
But you have to pick the minimum TLS version before the client has
sent that... Basically we have to make the choice long before we've
even started looking at pg_hba.
It would be good to have a way to do it, but I'm not sure pg_hba.conf
is the place for it.
