Hello there

I try to restore database from 15 version to 16 version I got this error

Database restore error: operator does not exist: character varying ->> unknown LINE 1: SELECT *, name->>'en_US' AS name FROM ir_model WHERE state =... ^ HINT: No operator matches the given name and argument types. You might need to add explicit type casts.

You cannot restore V 15 DB to V16 because there is many changes in the DB table structure between the versions, To do that you need to upgrade the DB from 15 to 16. If you have Enterprise subscription you can do use it to upgrade your DB and you will find more details in the below links: 

Upgrade Homepage | Odoo Upgrade

Upgrade — Odoo 16.0 documentation

If you don't have Enterprise subscription, you can use OCA  OpenUpgrade but unfortunately the version 16 is not available yet.


Note: The Odoo Enterprise upgrade to Odoo 16 is not available for production.

Also - if you are running into this error when trying to import a v15 database to your v15 Instance like me. Double check if there is no v16 running concurrently that is blocking the server-ports - that had cost me a lot of time to figure out ;-).
