PostgreSQL does not have parallel hints (or any hint in comments), so you are just changing a comment in the queries, which changes nothing at all in the execution plan. Unless you are not using vanilla PostgreSQL or you have some extension in place, in which case you didn't provide enough information. Best regards, -- Matheus de Oliveira
