It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
## Upgrade
## 2.0.0
In this version, this **chart depends on PostgreSQL 11 instead of PostgreSQL 10**. You can find the main difference and notable changes in the following links: [https://www.postgresql.org/about/news/1894/](https://www.postgresql.org/about/news/1894/) and [https://www.postgresql.org/about/featurematrix/](https://www.postgresql.org/about/featurematrix/).
For major releases of PostgreSQL, the internal data storage format is subject to change, thus complicating upgrades, you can see some errors like the following one in the logs:

In this case, you should migrate the data from the old PostgreSQL chart to the new one following an approach similar to that described in [this section](https://www.postgresql.org/docs/current/upgrading.html#UPGRADING-VIA-PGDUMPALL) from the official documentation. Basically, create a database dump in the old chart, move and restore it in the new one.
