Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
dbt
- Free tier severely limited to one developer seat and 3,000 models/month
- Starter plan at $100/user/month for each additional seat adds costs for team collaboration
- Requires existing data warehouse; not suitable for teams without cloud warehouse investment
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
