I deployed a new version of my application and it was not behaving correctly. After investigating I found out it was because I’m using some PostgreSQL jsonb methods that are available in PostgresSQL version 12 and 13 but not in version 11.
I read the Render documentation about PostgreSQL versions (Databases | Render · Cloud Hosting for Developers) and it says:
The major version for your database is fixed when it is created. We don’t do major database version upgrades without your permission, because it can be unsafe to do so .
All new databases are created with PostgreSQL version 11.
How can I upgrade my database to the latest version? or at least version 12.
Is it performed by Render as the documentation states?
Thank you for your support.
