The short version

  • Each has a real cost: PostgreSQL requires manual scaling across multiple machines for very large deployments; Structured no monthly view available, only daily and weekly views, limiting ability to preview long-term schedules
  • They diverge on capability: PostgreSQL covers ACID Compliance, Structured covers Visual timeline.
