Revision 73

_{Thursday, April 20, 2023}

Dear community,

We’d like to announce that Canonical’s newest Charmed PostgreSQL operator for Kubernetes has been published in the 14/stable channel.

If you are jumping over several stable revisions, make sure to check previous release notes before upgrading to this revision.

Features you can start using today

• Deploying on Kubernetes (tested with MicroK8s, GKE)
• Scaling up/down in one simple juju command
• HA using Patroni
• Full backups and restores are supported when using any S3-compatible storage
• TLS support (using “tls-certificates” operator)
• DB access outside of Juju using “data-integrator”
• Data import using standard tools e.g. “PostgreSQL Data Injector”
• Documentation

Inside the charms

• Charmed PostgreSQL K8s charm ships the latest PostgreSQL “14.7-0ubuntu0.22.04.1”
• K8s charms based on our ROCK OCI (Ubuntu LTS “22.04” - ubuntu:22.04-based)
• Principal charms supports the latest LTS series “22.04” only.
• Subordinate charms support LTS “22.04” and “20.04” only.

Technical notes

Compatibility with legacy charms:

• The new PostgreSQL charm is also a juju interface-compatible replacement for legacy PostgreSQL charms (using legacy interface pgsql, via endpoints db and db-admin). However, it is highly recommended to migrate to the modern interface postgresql_client (endpoint database).
  • Please contact us if you are considering migrating from other “legacy” charms not mentioned above.
• Charm PostgreSQL K8s charm follows the SNAP track “14” (through repackaed ROCK/OCI image).
• No “latest” track in use (no surprises in tracking “latest/stable”)!
  • Charmed PostgreSQL K8s charms provide legacy charm through “latest/stable”.
• Charm lifecycle flowchart diagrams: PostgreSQL.
• Modern interfaces are well described in “Interfaces catalogue” and implemented by ‘data-platform-libs’.
• Known limitation: PostgreSQL extensions are not yet supported.
