   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   I would like to see metrics for a query and I don't remember how to do that so I looked in the documentation but could not find any references to metrics, other than in the changelog. I ran `find . -name "*.md" -exec grep -Hi metrics {} \;`.
   
   **Describe the solution you'd like**
   Documentation, preferably in the user guide, on how to enable metrics.
   
   **Describe alternatives you've considered**
   None
   
   **Additional context**
   None

   This could perhaps start with showing `EXPLAIN` and then `EXPLAIN ANALYZE` to show the metrics and how to interpret them
