How does patroni can do some self healing after primary db gets down and then up again? Or is manual intervention required? How does it look?

manual intervention is not required. Patroni will just use a Standby as the new master. If the old master will be alive again it will be started as a backup. Of course there might be dataloss if it was used with async replication.

Patroni has great docs for this here: https://patroni.readthedocs.io/en/latest/replication_modes.h... (Actually this is more or less a thing to do with Postgres)
