At the beginning the patch did exactly that (at the node level), but it
lead to many
reports for the same query and it was suggested that query level results
would be
better.

For this feature, my idea was to have a way to get informations on
parallelism during
audits. Changing the log level would not be appropriate for this in my
opinion. I view
it as another tool to investigate a specific area: like log_temp_files etc..
Both solutions where proposed here:
