Fun with pg_checksums
The Postgres Operator easily lets you automate your Postgres in Kubernetes, whether it's one or thousands of instances.
Integrated high availability PostgreSQL solution for enterprises with always on requirements.
Hardened, secure, access controlled PostgreSQL to meet advanced security requirements.
Data checksums are a great feature in PostgreSQL. They are used to detect any corruption of the data that Postgres stores on disk. Every system we develop at Crunchy Data has this feature enabled by default. It's not only Postgres itself that can make use of these checksums. Some third party tools such as the awesome pgBackRest program can also use them for enhanced data integrity.
Sadly, enabling data checksums is still not the default behavior when creating a new Postgres cluster. When you invoke the initdb program, add the ‑‑data‑checksums flag (or ‑k if you prefer obscure arguments), and your shiny new Postgres cluster will have data checksums enabled.
