AI help for debugging RLS query errors (assistant CTA in tester)

Row-Level Security (RLS) in Postgres and managed Cloud SQL is a frequent source of opaque "permission denied" failures that block feature development and slow releases, and these problems mainly hit backend developers, platform engineers and security teams who manage data access policies. With roughly 20 million professional developers and more teams running managed Postgres, engineers can spend hours to days debugging interactions between roles, policies and session variables, often reproducing issues manually in staging or by adding permissive logs. You could build an LLM-assisted assistant embedded in the tester/console (an "assistant" CTA in the test runner) that ingests schema, RLS policies, query text and session bindings, then simulates policy evaluation to produce a concise root cause, a minimal repro and a suggested policy change or test snippet. Core features would include deterministic policy simulation (to avoid hallucinations), a policy-aware query analyzer, secure read-only connectors to managed DBs, and IDE/CI integrations that let teams re-run tests or apply suggested fixes automatically. In validated cases this could cut mean time to resolution from hours to minutes by surfacing precise fixes (for example, detecting a current_user() mismatch and generating an audited patch plus unit test). The market timing is favorable: the addressable developer and DB tooling market is about $8.0B (20M devs × $400 avg spend), the Market Score is 92/100 and Revenue Potential 82/100, while LLM integration, cloud-native DB adoption and shift-left security trends all increase demand for this class of tooling. You can differentiate by focusing on deterministic, auditable RLS simulation and enterprise-grade security rather than generic LLM explanations, but expect challenges around avoiding hallucinations, obtaining secure access to sensitive schemas, supporting multiple SQL dialects, and building the trust and test coverage required for enterprise adoption.
