Can you describe the trade-offs between different database indexing strategies?
Use the supplied PostgreSQL benchmark data to compare each strategy quantitatively. Include strategies without qualifying benchmark runs so the result reflects both measured performance and missing evidence.
strategy_name, index_method, index_size_mb, benchmark_count, avg_read_latency_ms, avg_write_latency_ms, and tradeoff_score.NULL for unavailable averages or scores.| Column | Type | Description |

| index_size_mb | DECIMAL(10,2) | Estimated storage consumed by the index |
| write_overhead_pct | DECIMAL(5,2) | Estimated percentage of write overhead |
| notes | VARCHAR(255) | Optional strategy notes |
| Column | Type | Description |
|---|---|---|
