  • Each has a real cost: Kustomer pricing not published; requires customised sales assessment and quote for exact costs; PostgreSQL requires manual scaling across multiple machines for very large deployments
  • They diverge on capability: Kustomer covers Unified customer view, PostgreSQL covers ACID Compliance.

  • Customisation-based pricing structure means no transparent cost comparison with competitors

PostgreSQL

  • Requires manual scaling across multiple machines for very large deployments
  • Performance tuning requires deep knowledge of database internals
  • No built-in graphical admin interface; command-line tools are primary method
