4.5.1

Crunchy Data announces the release of the PostgreSQL Operator 4.5.1 on November 13, 2020.

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

PostgreSQL Operator 4.5.1 release includes the following software versions upgrades:

  • PostgreSQL is now at versions 13.1, 12.5, 11.10, 10.15, 9.6.20, and 9.5.24.
  • Patroni is now at version 2.0.1.
  • PL/Perl can now be used in the PostGIS-enabled containers.

Changes

  • Simplified creation of a PostgreSQL cluster from a pgcluster resource. A user no longer has to provide a pgBackRest repository Secret: the Postgres Operator will now automatically generate this.
  • The exposed ports for Services associated with a cluster is now available from the pgo show cluster command.
  • If the pgo-config ConfigMap is not created during the installation of the Postgres Operator, the Postgres Operator will generate one when it initializes.
  • Providing a value for pgo_admin_password in the installer is now optional. If no value is provided, the password for the initial administrative user is randomly generated.
  • Added an example for how to create a PostgreSQL cluster that uses S3 for pgBackRest backups via a custom resource.

Fixes

  • Fix readiness check for a standby leader. Previously, the standby leader would not report as ready, even though it was. Reported by Alec Rooney (@alrooney).
  • Proper determination if a pgcluster custom resource creation has been processed by its corresponding Postgres Operator controller. This prevents the custom resource from being run by the creation logic multiple times.
  • Prevent initdb (cluster reinitialization) from occurring if the PostgreSQL container cannot initialize while bootstrapping from an existing PGDATA directory.
  • Fix issue with UBI 8 / CentOS 8 when running a pgBackRest bootstrap or restore job, where duplicate “repo types” could be set. Specifically, the ensures the name of the repo type is set via the PGBACKREST_REPO1_TYPE environmental variable. Reported by Alec Rooney (@alrooney).
  • Ensure external WAL and Tablespace PVCs are fully recreated during a restore. Reported by (@aurelien43).
  • Ensure pgo show backup will work regardless of state of any of the PostgreSQL clusters. This pulls the information directly from the pgBackRest Pod itself. Reported by (@saltenhub).
  • Ensure that sidecars (e.g. metrics collection, pgAdmin 4, pgBouncer) are deployable when using the PostGIS-enabled PostgreSQL image. Reported by Jean-Denis Giguère (@jdenisgiguere).
  • Allow for special characters in pgBackRest environmental variables. Reported by (@SockenSalat).
  • Ensure password for the pgbouncer administrative user stays synchronized between an existing Kubernetes Secret and PostgreSQL should the pgBouncer be recreated.
  • When uninstalling an instance of the Postgres Operator in a Kubernetes cluster that has multiple instances of the Postgres Operator, ensure that only the requested instance to be uninstalled is the one that’s uninstalled.
  • The logger no longer defaults to using a log level of DEBUG.
