matrix_mautrix_hangouts_database_engine has been set to `postgres` (which is our new default now).
However, we've discovered an existing SQLite database in {{ matrix_mautrix_hangouts_sqlite_database_path_local }}.
It appears that you've been using this bridge with the SQLite engine until now.
To continue using SQLite, opt into it explicitly: add `matrix_mautrix_hangouts_database_engine: sqlite` to your vars.yml file and re-run this same command.
Alternatively, to migrate your existing SQLite database to Postgres:
1. Stop all services (`ansible-playbook -i inventory/hosts setup.yml --tags=stop`)
2. Import the SQLite database into Postgres (`ansible-playbook -v -i inventory/hosts setup.yml --tags=import-generic-sqlite-db --extra-vars='sqlite_database_path={{ matrix_mautrix_hangouts_sqlite_database_path_local }} postgres_connection_string_variable_name=matrix_mautrix_hangouts_database_connection_string'`)
3. Re-run the playbook (`ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start`)
