What's Next?

The patterns here are just the start. Some directions worth exploring:

• 
  — RAG-based NL2SQL with self-learning capabilities


• 
  pgai — Timescale's extension for running ML directly inside PostgreSQL


• 
  Multi-agent SQL workflows — agents that collaborate across multiple databases

The line between "database" and "AI system" is getting thinner every month. If you're already running PostgreSQL, you're closer to a production AI stack than you might think.
