def new_posts_since_summary
  # Postgres uses discrete range types for int4range, which means
  # (1..2) is stored as (1...3).
  #
  # We use Range#max to work around this, which in the case above always returns 2.
  # Be careful with using Range#end here, it could lead to unexpected results as:
  #
  # (1..2).end => 2
  # (1...3).end => 3
