msg: >-
matrix_appservice_discord_database_engine has been set to `postgres` (which is our new default now).
However, we've discovered an existing SQLite database in {{ matrix_appservice_discord_data_path }}/{{ matrix_appservice_discord_database_filename_name }}.
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 migrate to Postgres: TODO - migration instructions here.
