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