My idea was to have PostgreSQL output tips to help performance. The
TODO item is:* Add SET PERFORMANCE_TIPS option to suggest INDEX, VACUUM, VACUUM ANALYZE, and CLUSTER
I also will be writing an article on performance tuning this month.
What parameters would these options you suggest control? I usually
prefer options that have more concrete effect.
