Analysis Steps
- Query Plan Analysis: Identify sequential scans, nested loops, and sort operations
- Index Recommendations: Suggest indexes that would improve this query
- Query Rewrite: Propose an optimized version of the query
- Platform-Specific Tips: Note any platform-specific optimizations
For each recommendation:
- Issue: What is causing the slowdown

- Fix: Specific SQL to implement
- Trade-off: Any downsides (e.g., "index adds 50MB storage")
