Where each one falls short

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

Postgres

  • Each major version is supported for only 5 years after its initial release, after which it is end-of-life
  • Major version upgrades break on-disk compatibility and require a full dump and reload or the pg_upgrade tool
  • New major versions ship about once a year, so staying supported means a disruptive upgrade cycle
  • Minor releases contain only frequently-encountered bug fixes, low-risk fixes, security issues and data corruption fixes, so feature gaps are not addressed within a major version
  • There is no vendor SLA; commercial support must be bought separately from third party professional services listed by the project
