Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Microsoft Power Automate

  • Free plan limited to 750 flow runs/month and standard connectors only; premium connectors require paid plans
  • Not suitable for long-running workflows; can fail unexpectedly without warning
  • Limited to simple linear logic; fails with complex workflows involving multiple stakeholders
  • Tasks cannot automate at scale when requiring more than approximately 60 users

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
