    ## BE *VERY* CAREFUL WHEN EDITING!
    ## YAML FILES ARE SUPER SUPER SENSITIVE TO MISTAKES IN WHITESPACE OR ALIGNMENT!

      ## will be set automatically by bootstrap based on detected RAM, or you can override

      ## can improve sorting performance, but adds memory usage per-connection
      #db_work_mem: "40MB"

      #version: tests-passed
