Crunchy Data announces the release of the PostgreSQL Operator 4.6.1 on February 16, 2021.

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

PostgreSQL Operator 4.6.1 release includes the following software versions upgrades:

  • PostgreSQL is now at versions 13.2, 12.6, 11.11, 10.16, and 9.6.21.

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.


  • 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.
  • The post-cluster creation pgBackRest tasks, i.e. creating a stanza and creating an initial backup, are now deleted by the Operator should they complete successfully. Besides good housekeeping, this provides a workaround for an OpenShift 3.11 bug that was causing the Operator to continuously issue pgBackRest backups during an OpenShift refresh cycle. Reported by Paul Heinen (@v3nturetheworld).


  • Only attempts to start scheduled backups in running pgBackRest repository Pods. Reported by Satria Sahputra (@satriashp).
  • Support the substitution for the limit on the number of queries to include the the pg_stat_statements support of pgMonitor. Defaults to 20, which is the pgMonitor upstream value. Contributed by Steven Siahetiong (@ssiahetiong).
  • On initialization, check that primary PostgreSQL Deployment is created before attempting to scale.
  • 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).
  • Fix crash when attempting to create a cluster via the REST API and no custom labels were set. Reported by Jeffrey den Drijver (@JeffreyDD)
  • Ensure a pgBadger sidecar is not added to a PostgreSQL cluster after a pgo upgrade if it was not previously specified.
  • Ensure superfluous labels are deleted during a pgo upgrade.
  • Remove /crunchyadm from unix_socket_directories configuration during a pgo upgrade. Reported by Steven Siahetiong (@ssiahetiong).
  • Ensure updated paths, i.e. rename to /opt/crunchy, are reflected in cluster ConfigMap when running pgo upgrade. Reported by Steven Siahetiong (@ssiahetiong).
  • Ensure value from --ccp-image-tag is applied when running pgo upgrade.
  • Ensure the pgBackRest repository sets ownership settings to the pgbackrest user, which, while not noticed under most operating environments, could manifest itself in different UID modes. Reported by Matt Russell (@mjrussell).
