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 endpointsdbanddb-admin). However, it is highly recommended to migrate to the modern interfacepostgresql_client(endpointdatabase).- 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.
