Page 30: "The workers saved the data in their partition to the database. In our scenario, we had
four workers, this means four connections to the database when we saved the data. "

This is not correct. Connections to Postgres are per tasks or partitions. Here there are 3 workers in the picture but there are four partitions or tasks. So four connections are each per task or partition not per worker.
