I suspect the real purpose here is to easily reject non-SSL connections
altogether. This is currently quite cumbersome and requires careful
ongoing maintenance of pg_hba.conf. But I see two problems with the
proposed approach: (1) initdb doesn't support setting up SSL, so the
only thing you can achieve here is to reject all TCP/IP connections,
until you have set up SSL. (2) The default pg_hba.conf only covers
localhost connections. The value of enforcing SSL connections to
localhost is probably quite low. You still need ongoing careful
pg_hba.conf maintenance as you add more host entries.
Maybe we just need something like libpq's sslmode on the server side.
Probably not quite the same, perhaps just ssl = require.
