The Postgres Operator has been developed at Zalando and is being used in
production for over three years.

## Using Spilo 12 images or lower
## Supported Postgres & K8s versions

If you are already using the Postgres operator in older version with a Spilo 12 Docker image you need to be aware of the changes for the backup path.
We introduce the major version into the backup path to smoothen the [major version upgrade](docs/administrator.md#minor-and-major-version-upgrade) that is now supported.

The new operator configuration can set a compatibility flag *enable_spilo_wal_path_compat* to make Spilo look for wal segments in the current path but also old format paths.
This comes at potential performance costs and should be disabled after a few days.

The newest Spilo image is: `ghcr.io/zalando/spilo-15:2.1-p9`

The last Spilo 12 image is: `registry.opensource.zalan.do/acid/spilo-12:1.6-p5`
