Fix Database Issues with Claude Code
Claude Code can review and optimize database schemas, add RLS policies, and fix query patterns.
About This Problem
AI-generated database schemas often lack proper indexes, have no Row Level Security, use inefficient query patterns, and create data integrity problems. These issues worsen as your app grows.
Common Symptoms
- Queries getting slower as data grows
- Missing Row Level Security on Supabase tables
- N+1 query patterns causing excessive database load
- No data validation at the database level
- Missing foreign key constraints or cascading deletes
- Migrations that break existing data
DIY Fix Steps
Enable Row Level Security on ALL Supabase tables
Add indexes on columns used in WHERE, ORDER BY, and JOIN clauses
Replace N+1 queries with JOINs or batch fetches
Add NOT NULL constraints and check constraints where appropriate
Set up foreign keys with proper cascade rules
Use database migrations instead of manual schema changes

FAQ
Why do AI tools create poor database schemas?
AI tools design schemas for quick functionality, not long-term scalability. They skip indexes because queries are fast with small datasets, omit RLS because it adds complexity, and use simple query patterns that degrade at scale.
