• there is an autofixer for database schemas

Context

• Jupyter Server version: 4.x

For example, jupyterhub uses alembic for migrating database between versions (https://github.com/jupyterhub/jupyterhub/tree/main/jupyterhub/alembic/versions).

@andrii-i is working on this right now in #520. Thank you Mike for opening an issue to track this.

@krassowski thank for opening this issue. I just released v2.7.0 that among other things adds a database migration / table extension logic (#520).
