My current database differs from what alembic expects, I think because the database was changed manually.
I thought I could just autogenerate a new revision that fixes the changes but get an error.

Is there an easy way to fix the current changes? Ideally automatically via alembic since there are a lot of changes.

Worst case I can start from scratch, but it would be great to be able to just generate a script that gets rid of the changes only.

# alembic heads

# alembic revision --autogenerate -m "fix last migration"
Target database not consistent with current codebase:
