EDB Postgres for Kubernetes 1.13.0 release notes v1
We are in the process of migrating the documentation from the previous EDB Postgres for Kubernetes name to the new EDB CloudNativePG Cluster name. You may see references to both names in this documentation.
Released: 17 Feb 2022
This release of EDB Postgres for Kubernetes includes the following:
| Type | Description |
|---|---|
| Feature | Support for Snappy compression. Snappy is a fast compression option for backups that increase the speed of uploads to the object store using a lower compression ratio. |
| Feature | Support for tagging files uploaded to the Barman object store. This feature requires Barman 2.18 in the operand image. of backups after Cluster deletion. |
| Feature | Extension of the status of a Cluster with status.conditions. The condition ContinuousArchiving indicates that the Cluster has started to archive WAL files. |
| Feature | Improve the status command of the cnp plugin for kubectl with additional information: add a Cluster Summary section showing the status of the Cluster and a Certificates Status section including the status of the certificates used in the Cluster along with the time left to expire. |
| Feature | Support the new barman-cloud-check-wal-archive command to detect a non-empty backup destination when creating a new cluster. |
| Feature | Add support for using a Secret to add default monitoring queries through MONITORING_QUERIES_SECRET configuration variable. |
| Feature | Allow the user to restrict container’s permissions using AppArmor (on Kubernetes clusters deployed with AppArmor support). |
| Feature | Add Windows platform support to cnp plugin for kubectl, now the plugin is available on Windows x86 and ARM. |
| Feature | Drop support for Kubernetes 1.18 and deprecated API versions |
| Container images | PostgreSQL containers include Barman 2.18. |
| Security fix | Add coherence check of username field inside owner and superuser secrets; previously, a malicious user could have used the secrets to change the password of any PostgreSQL user. |
| Bug fix | Fix a memory leak in code fetching status from Postgres pods. |
| Bug fix | Disable PostgreSQL self-restart after a crash. The instance controller handles the lifecycle of the PostgreSQL instance. |
| Bug fix | Prevent modification of spec.postgresUID and spec.postgresGID fields in validation webhook. Changing these fields after Cluster creation makes PostgreSQL unable to start. |
| Bug fix | Reduce the log verbosity from the backup and WAL archiving handling code. |
| Bug fix | Correct a bug resulting in a Cluster being marked as Healthy when not initialized yet. |
| Bug fix | Allows standby servers in clusters with a very high WAL production rate to switch to streaming once they are aligned. |
| Bug fix | Fix a race condition during the startup of a PostgreSQL pod that could seldom lead to a crash. |
| Bug fix | Fix a race condition that could lead to a failure initializing the first PVC in a Cluster. |
| Bug fix | Remove an extra restart of a just demoted primary Pod before joining the Cluster as a replica. |
| Bug fix | Correctly handle replication-sensitive PostgreSQL configuration parameters when recovering from a backup. |
| Bug fix | Fix missing validation of PostgreSQL configurations during Cluster creation. |
