EDB Postgres Failover Manager 3.9
WHAT’S NEW
This update is notifying you of a new software release, EDB Postgres Failover Manager (EFM)
version 3.9. Failover Manager provides high availability infrastructure for EDB Postgres clusters.
Failover Manager monitors the members of a Postgres cluster, identifies and verifies database
failures quickly and reliably, and if needed promotes a standby node to become the cluster
master and issues alerts.
Highlights of this release include:
| Features | Benefits |
| Reduce num_sync on primary - EFM can reduce the num_sync value for synchronous replicas when standbys leave the cluster so that the primary can still accept writes. | The primary server is not locked, and remains available to accept writes even when synchronous standbys have failed or left the cluster. |
| EDB Postgres Replication Server Integration (EPRS)- EFM 3.9 includes features to work with new EDB replication server to allow clusters with a mix of physical and logical replication. | Customers have the flexibility to use both physical and logical replication in the same Postgres cluster for high write and read availability. |
| Changes to algorithm used to select standby to promote - When there are multiple standbys, EFM can promote based on current replay value instead of standby priority. | Reduces the time needed to promote standby in cases where standbys are lagging behind the old master, which may occur when the promotion is based on predefined priority. |
| EDB Postgres Advanced Server and PostgreSQL v12 support on Debian/Ubuntu - EFM now handles database file layouts on Debian/Ubuntu installations. | Adds support for Debian/Ubuntu |
This release also includes fixes for the following issues:
- A fix for ssl connections requiring hostname validation. 957322
- Handling equals sign in recovery conf information. 963294
