"Hi Thomas, saw your Postgres query timeout on 10M rows—I optimized execution plans with composite partial indexes, slashing query runtime from 14s to 45ms."
Why it works: Mentions Postgres timeouts on 10M rows, EXPLAIN ANALYZE, and a 14s to 45ms reduction.

Hi Thomas,
Saw your posting regarding slow database queries causing connection pool starvation under heavy web traffic. I am a database performance engineer with deep expertise in PostgreSQL query planning and index architecture.
Here is the optimization roadmap:
1. Run `EXPLAIN (ANALYZE, BUFFERS)` to detect sequential scans, memory spills, and inefficient nested loops.
2. Create targeted partial and covering B-Tree / GIN indexes tailored precisely to your application filter patterns.
3. Tune PostgreSQL configuration (`work_mem`, `shared_buffers`, `effective_cache_size`) to match your server hardware.
I can diagnose your top 3 slowest queries within 2 hours. Would you like to share the query logs?
Best,
[Your Name]
