5.7.1

Features

• The operator emits a warning event when a postgrescluster is using a major version of Postgres that is no longer receiving updates

Changes

• Patroni is now at version 3.3.4.

Fixes

5.7.0

Features

• Asynchronous archiving by default. CPK will take control of the spool-path. If you have set the spool-path in the backups.pgbackrest.global section of your spec, remove that setting after upgrading. You can also delete that directory. If you would like to opt out of asynchronous archiving, set spec.backups.pgbackrest.global.archive-async: "n". After upgrading, a new log will be introduced to track WAL archiving at pgdata/pgbackrest/log/db-archive-push-async.log.
• You can now enable backups from replicas within your pgBackRest configuration. Ensure you have at least one Postgres replica available, and then set spec.backups.pgbackrest.global.backup-standby: "y".
• You can now disable backups when provisioning new Postgres cluster by omitting the backups section from your PostgresCluster spec.
• You can now use Kerberos authentication with pgAdmin4 deployments created via the PGAdmin API.
• Liveness and readiness probes are now enabled by default when the operator is run. Additionally, all CPK installers have been updated to use these probes when creating the operator Deployment.
• You can now make the operator highly available by adding one or more additional replicas to the pgo Deployment.
• You can now configure the operator to watch a certain subset of namespaces using the new PGO_TARGET_NAMESPACES environment variable. This means you can now configure the operator to watch one namespace, all namespaces, or a specific subset of namespaces.
• You can now provide a custom CA cert for Postgres LDAP authentication using the existing spec.config.files method to mount a Secret containing the ca.crt file.
• You can now easily enable or disable CPK feature gates via values.yaml settings when installing CPK via Helm. Contributed by Daniel Holmes (@jaitaiwan)
• You can now leverage Kubernetes Volume Snapshots when cloning a PostgresCluster. Enable VolumeSnapshots feature gate in your operator installation, and then configure a VolumeSnapshotClass within the spec of your source PostgresCluster using spec.backups.snapshots.volumeSnapshotClassName. Now when you clone the PostgresCluster, a snapshot will be leveraged to reduce the overall time to create and initialize the clone.
