  1. Add panels that utilize the columns that, for some reason, were not used in the index_stats metric:
    • Top n indexes by disk reads (blocks)
    • Top n indexes by cache hits (blocks)
    • Top n indexes by tuples read
    • Top n indexes by tuples fetched
  2. Update the Top n biggest indexes to return the number of scans that happened in the specified time interval instead of the total scans since index creation.
