Hi,
You can use repmgr or patroni
Repmgr can do what you want but it is not just by executing repmgr command. You have to run a daemon "repmgrd" on all
nodes.Then you should activate automatic failover...
Note that a witness is not necessary to do that but it could be useful depending on what you are searching...

Objet : Failover / repmgr questions
All;
we are constructing a PostgreSQL based architecture that is more complex than "promote node B and manage the IP" for a
failover.
It would be ideal if I could deploy repmgr and have repmgr run a script for me if it detects a failure, but it looks
likethis may not be an option. Anyone know if I can force repmgr to do this? Is there a better tool that does?
Thanks in advance
