This is the third and last part of blog articles dedicated to pg_rewind. In the two previous articles we have seen how pg_rewind is useful to fix split-brain events due to mistakes in the switchover procedures, avoiding the need of new base backups.

In the previous blog article we have seen how pg_rewind works with a simple HA cluster, composed of a master node replicating to a standby.
