The short version
- Each has a real cost: PostgreSQL requires manual scaling across multiple machines for very large deployments; RudderStack on the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
- They diverge on capability: PostgreSQL covers ACID Compliance, RudderStack covers Data collection.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
RudderStack
- On the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
- The free plan allows 250,000 events a month
- Growth starts at $265 a month for 1 million events, with volume sold in tiers up to 25 million
- Overage is charged as the gap to the next tier's price rather than per event, so a small excess costs a full tier step
