• Activity snapshot: Track timestamp of previous activity snapshot
• Support setting custom AWS endpoints using environment variables
• Increase allowed characters for pid field to 7 (for 64-bit systems)
  • This supports environments where pid_max is set to 4194304 instead of 32768
  • Note that this means continuity with old backend/vacuum identities is lost
    i.e. data might show up incorrectly for existing processes after the upgrade
