Обсуждение: CPU Configuration - postgres
Hi Team,
Could you please confirm whether I need to restart my postgresql instance after adding CPU to my server.
Is there any configuration in postgresql that restrict the number of CPU usage by postgres process.

For parallelism, there are these options: - max_parallel_workers_per_gather - max_parallel_workers - max_worker_processes Where the first two essentially can limit the amount of cores to be used. Is that what you were asking for?

That only matters if you want to use those extra cores to make individual queries / commands faster.
If all OP cares about is "will PG use my extra cores", the answer is yes it will without doing anything special.
