Hello,

Thanks for those info, now we know what to do.

Hi,

1. If you’re on Odoo Online (SaaS at odoo.com)

    The Delete button for expired databases often disappears.

    You cannot drop it yourself; only Odoo SA can.

    Solution: open a Support Ticket from your Odoo.com account and request deletion.

2. If you’re on Odoo.sh

    Go to your Odoo.sh project → Databases tab.

    You’ll see all staging/production databases.

    There’s a trash/delete icon next to databases (unless expired).

    If not visible, you may need to archive the branch linked to it, which will remove the related database.

3. If you’re On-Premise (self-hosted)

You have full control via the database manager or command line:

    Database Manager (Web UI):

        Go to https://yourdomain.com/web/database/manager

        Log in with the master password

        Select your dummy database → Click Delete

    Command Line (PostgreSQL):

    # list databases

    psql -U odoo -l

    # drop the dummy db

    dropdb -U odoo dummy_db_name

Hope it helps
