Thank you :)

I finally changed:

|How does PostgreSQL use CPU resources?
|The PostgreSQL server is process-based (not threaded). Each database session
|connects to a single PostgreSQL operating system (OS) process. Multiple
|sessions are automatically spread across all available CPUs by the OS. The OS
|also uses CPUs to handle disk I/O and run other non-database tasks. Client
|applications can use threads, each of which connects to a separate database
|process. Since version 9.6, portions of some queries can be run in parallel, in
|separate OS processes, allowing use of multiple CPU cores. Parallel queries are
|enabled by default in version 10 (max_parallel_workers_per_gather), with
|additional parallelism expected in future releases.
