It appears that you've been using this bridge with the SQLite engine until now. 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_appservice_discord_database_engine: sqlite` to your vars.yml file. To continue using SQLite, opt into it explicitly: add `matrix_appservice_discord_database_engine: sqlite` to your vars.yml file and re-run this same command.
To migrate to Postgres: TODO - migration instructions here. 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_appservice_discord_sqlite_db_path }} postgres_db_connection_string={{ matrix_appservice_discord_database_connString }}'`)
3. Re-run the playbook (`ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start`)
