> The parallelism happens even if my PC has only one processor?

PostgreSQL creates a separate process for each client connection -
whether you have one CPU or more.

> Each query is executed in a separeted Thread?
No threads, at least on Unix. Regular processes (sometimes called backends).

If this client uses two connections, you can run two queries in paralell.
