The whitepaper "EDB Postgres Distributed: The Next Generation of Postgres High Availability" discusses the evolution of HA technology, emphasizing near-zero downtime maintenance. It introduces PGD, focusing on logical replication for EHA in Postgres clusters. PGD's key features include mesh-based multi-master architecture, conflict management, and Always On configurations for failover. It overcomes limitations of traditional replication methods like PNLR, offering automatic DDL and DML replication, advanced conflict resolution, and integration with backup solutions. PGD ensures 99.999% database availability, making it the industry-leading solution for EHA in Postgres.
