This page describes how to upgrade the major version of your PostgreSQL database.

Preparations ¶

Before doing a major version upgrade, consult the Google Cloud SQL documentation for any preparation that needs to be done.

Choose a new major version ¶

Select a new major version of PostgreSQL that you want to upgrade to. For safe upgrades, it is recommended to only do one major version at a time.

The full list of supported versions can be found in the application spec reference.

Change the major version ¶

To change the major version, modify the type field in your application manifest:

spec:
  gcp:
    sqlInstances:
      - type: POSTGRES_17

Commit and push the changes to your application repository.

The upgrade will start the next time you deploy your application.
