PostgreSQL 19's delay shows the new bottleneck: deciding which AI findings matter

PostgreSQL 19 is now expected around November 19. One of its committers, Peter Eisentraut, wrote that LLM-assisted code review was surfacing defects faster than the team could fix them, and roughly 8 to 10 significant features were reverted from the 19 branch after beta began. (The Register ran it as "AI reviewers delayed Postgres"; the project's own reasons are a bit more nuanced, but the pattern is worth noticing.)

Finding problems got cheap

A year ago the scarce thing was a careful reviewer. Now you can point several models at the same change and get a long list of concerns in minutes. That is great, until the list is longer than your week.

The hard part has moved:

  • Which of these findings are real, and which are a model being confidently wrong?
  • Which ones actually block a release, and which can wait?
  • Who owns that call?

What I do as a solo builder

I build Brainstorm, a Linux app (1.0.1) where several AIs discuss the same goal. The workflow I ended up with is boring on purpose:

  1. Let more than one model argue about the plan, so disagreement shows up early instead of in review.
  2. Keep the check separate from the agents that wrote the draft, so "it ran smoothly" doesn't get mistaken for "it's right".
  3. Nothing reaches the project's main branch until a human approves it.

The point isn't more findings. It's a trail of who disagreed, what got checked, and who signed off.

You bring your own model accounts; I don't sell model credits.

If you're dealing with an AI review flood on your own projects, I'd like to hear how you triage it.
