  # Note on DB_POOL_SIZE:
  # -------------------------------------------------------------------------------------------------------------
  # To optimize for the simplest self-hosting setup, we run ActionCable, GoodJob, and Rails in the same process.
  # 
  # This requires DB connections for each:
  #
  #   Puma: Requires 3 connections (Rails default)
  #   ActionCable: 5 connections (Rails defaults to 4 workers + 1 listener for Postgres adapter)
  #   GoodJob: 15 connections to run in "async" mode.  See `good_job.rb` for the breakdown.
  #   --------------------------------------------------------------------------------------------
  #   Total: 23 connections
  #
  # We default to this value so that self-hosters don't need to configure anything.  Hosted mode will require
  # a different pool size, as we run ActionCable, GoodJob, and Rails in separate processes.
