I need to take actions when Postgres streaming replication failover occurred.  Is there a way to be notified when Postgres slave becomes master?  If no such notification possible, what is the best way to actively monitor which server is master.  My Postgres  is running inside Kubernetes and the HA is managed by Patroni.

 

Thanks!
