Assunto: How does Postgres decide if to use additional workers?
So, based on which facts does Postgres decide if to use aadditional
workers or not? Can I see those decisions explained somewhere? I don't
see anything in the query plan. Thanks!

Mit freundlichen Grüßen

Hi!

I think you should look into min_parallel_table_scan_size and min_parallel_index_scan_size  GUCs.
