Evolution Of PostgreSQL Replication and High Availability (upto ~ 99.999%)
summary
Claims Postgres‑BDR® can deliver 99.999% availability, supports rolling upgrades, and provides automatic DDL replication while running as an active‑active mesh. The talk names alternatives (Bucardo, SymmetricDS, Quest Shareplex, Oracle GoldenGate, EDB replication server), describes a platinum architecture with PG Bouncer HAProxy logical standby shadow master witness and Barman backups managed by TPAexec, and argues BDR replaces Oracle RAC in cloud and on‑prem scenarios with demonstrated failover and upgrade workflows.
