The short version

  • Each has a real cost: PostgreSQL requires manual scaling across multiple machines for very large deployments; Spline aI generation features produce inconsistent and often distorted results, failing at basic depth perception tasks
  • They diverge on capability: PostgreSQL covers ACID Compliance, Spline covers 3D modeling.

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

Spline

  • AI generation features produce inconsistent and often distorted results, failing at basic depth perception tasks
  • Limited to simpler designs - not suitable for high-poly, detailed production models
  • Performance degrades with complex scenes containing many objects and materials
  • Limited non-Apple platform coverage compared to cross-platform design tools
  • Tutorials are either too fast for beginners or too basic for advanced users
