Not smart but effective: restart the odoo server with a correct db-filter

In what situation do you need this functionality? Maybe before you start a specific action: like creating a test database, one must backup production and do a shutdown anyway.

You can use the --db-filter=db option to specify the default database.

Hello Luis, before you must take in care this: hide database selection is a security option in this scenario if you need access to database i recommend you use another web instance to manage this.

Answering your question this just dont list your databases in all options, you can clear cache and refresh page.
