Take a look at https://github.com/hapostgres/pg_auto_failover it's quite simple to use and manage. You can use libpq support for target_session_attrs (been there since Pg 10 - https://paquier.xyz/postgresql-2/postgres-10-libpq-read-writ... ) so you don't need active loadbalancer in front of your Pg cluster.

You can however create your own health/status check service on top of pg_autoctl show state and use HAProxy if required.

I don't think there's something easier to setup and manage than pg_auto_failover, Patroni always appeared very complicated to me.
