Connections to Postgres directly from an edge function are secured with SSL

If you use Deno Postgres or other Postgres clients to connect to your database instance from a Supabase Edge Function, those connections are now secured with SSL. You don't need to add any extra configurations to your client setup.

@laktek My MCU ESP32 client requires a RootCA certificate to connect to the SSL Supabase Edge Function. How do you obtain that?
