The Postgres Operator has been developed at Zalando and is being used in
production for over two years.
production for over three years.
## Notes on Postgres 13 support
If you are new to the operator, you can skip this and just start using the Postgres operator as is, Postgres 13 is ready to go.
The Postgres operator supports Postgres 13 with the new Spilo Image that includes also the recent Patroni version to support PG13 settings.
More work on optimizing restarts and rolling upgrades is pending.
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 smooth the major version upgrade that is now supported manually.
The new operator configuration, sets a compatilibty flag *enable_spilo_wal_path_compat* to make Spilo look in current path but also old format paths for wal segments.
This comes at potential perf. costs, and should be disabled after a few days.
The new Spilo 13 image is: `registry.opensource.zalan.do/acid/spilo-13:2.0-p1`
The last Spilo 12 image is: `registry.opensource.zalan.do/acid/spilo-12:1.6-p5`
