   Engineer: "HELP, our production DB is frozen on this query that worked fine before!"

   Infra: "Hmm, let's check... Well would you look at that, it seems like your LLM query planner usually works and produces fast queries, but this time when you changed a variable name to trigger query rebuild, it happened to hallucinate and miss an index, would you mind re-running the LLM a few times until you get a faster query?"

      This exact situation has happened to me with Postgres' stock query planner when an automatic analyze got a bad sample of a large table.
