4.4.3

on GitHub

Crunchy Data announces the release of the PostgreSQL Operator 4.4.3 on March 1, 2021.

The PostgreSQL Operator is released in conjunction with the Crunchy Container Suite.

The PostgreSQL Operator 4.4.3 release includes the following software versions upgrades:

• The PostgreSQL containers now use versions 12.6, 11.11, 10.16, 9.6.21, and 9.5.25

PostgreSQL Operator is tested against Kubernetes 1.17 - 1.20, OpenShift 3.11, OpenShift 4.4+, Google Kubernetes Engine (GKE), Amazon EKS, Microsoft AKS, and VMware Enterprise PKS 1.3+, and works on other Kubernetes distributions as well.

Changes

• When using the --restore-from option on pgo create cluster to create a new PostgreSQL cluster, the cluster bootstrap Job is now automatically removed if it completes successfully.
• The --compress-type flag is now supported for the backup options (--backup-opts) for pgBackRest backups with pgo backup. none, gz, bz2, and lz4 are all supported. Presently zst is not supported.
• Add the --no-prompt flag to pgo upgrade. The mechanism to disable the prompt verification was already in place, but the flag was not exposed. Reported by (@devopsevd).
• Removes certain characters that causes issues in shell environments from consideration when using the random password generator, which is used to create default passwords or with --rotate-password.
• Allow for the --link-map attribute for a pgBackRest option, which can help with the restore of an existing cluster to a new cluster that adds an external WAL volume.
• Revert setting "UsePAM" to "yes" by default as the bug fix in Docker that required that change was applied roughly one year ago.

Fixes

• Fix issue where pgo test would indicate every Service was a replica if the cluster name contained the word replica in it. Reported by Jose Joye (@jose-joye).
• Do not consider Evicted Pods as part of pgo test. This eliminates a behavior where faux primaries are considered as part of pgo test. Reported by Dennis Jacobfeuerborn (@dennisjac).
• Fix pgo df to not fail in the event it tries to execute a command within a dangling container from the bootstrap process when pgo create cluster --restore-from is used. Reported by Ignacio J.Ortega (@IJOL).
• pgo df will now only attempt to execute in running Pods, i.e. it does not attempt to run in evicted Pods. Reported by (@kseswar).
• Ensure the sync replication ConfigMap is removed when a cluster is deleted.
• Fix crash in shutdown logic when attempting to shut down a cluster where no primaries exist. Reported by Jeffrey den Drijver (@JeffreyDD).
• Fix syntax in recovery check command which could lead to failures when manually promoting a standby cluster. Reported by (@SockenSalat).
• Fix issue with pgo backup where it was unable to take a backup from a new primary after pgo failover was called. Reported by (@mesobreira).
• Do not trigger a backup if a standby cluster fails over. Reported by (@aprilito1965).
• Ensure archive_mode is forced to on when performing using the "restore in place" method. This ensures that the timeline is correctly incremented post-restore, which could manifest itself with various types of WAL archive failures.
• Generally improvements to initialization of a standby cluster.
• Ensure proper label parsing based on Kubernetes rules and that it is consistently applied across all functionality that uses labels. Reported by José Joye (@jose-joye).
• Remove legacy defaultMode setting on the volume instructions for the pgBackRest repo Secret as the readOnly setting is used on the mount itself. Reported by (@szhang1).
• Only attempts to start scheduled backups in running pgBackRest repository Pods. Reported by Satria Sahputra (@satriashp).
• Allow for Restart API server permission to be explicitly set. Reported by Aleksander Roszig (@AleksanderRoszig).
• Update pgo-target permissions to match expectations for modern Kubernetes versions.
• During a major upgrade, ensure permissions are correct on the old data directory before running pg_upgrade.
• Ensure major upgrades via crunchy-upgrade support PostgreSQL 12. Reported by (@lbartnicki92).
