Back to the Future Part 3: pg_rewind with PostgreSQL 9.6

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.

September 28, 2016/1 Comment/in 2ndQuadrant, Featured, Giuseppe's PlanetPostgreSQL /by 2ndQuadrant Press

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.
