Pending problems -

1. In word-worker, somehow, when inserting in the relation table, we are inserting the same (dataset_id, word_id) tuple multiple times in a single call to Postgres, this is not allowed when utilizing an on conflict do update.
2. Deadlocks with multiple word-workers, solvable by utilizing clickhouse instead of Postgres.
