Realtime Self-hosting Config

Port which you can connect your client/listeners

Connect to database via either IPv4 or IPv6. Disregarded if database host is an IP address (e.g. '127.0.0.1') and recommended if database host is a name (e.g. 'db.abcd.supabase.co') to prevent potential non-existent domain (NXDOMAIN) errors.
