/**
 * Performance Regression Tests
 *
 * These tests establish performance baselines for key operations in @dotdo/postgres-shared
 * and detect regressions when performance drops significantly.
 *
 * ## How Regression Detection Works
 *
 * 1. Each test measures operation timing with multiple iterations
 * 2. Statistical analysis (p50, p95, p99) provides robust metrics
 * 3. Results are compared against registered baselines with tolerance
 * 4. Tests fail if performance exceeds baseline by more than tolerance factor
 *
 * ## Adding New Baselines
 *
 * 1. Use measureTiming() to measure your operation
 * 2. Register a baseline with expected p50/p95 values
 * 3. Use custom matchers like toBeFasterThan() or toBeWithinBaseline()
 *
 * ## Environment Considerations
 *
 * - CI environments are typically slower than local development
 * - Baselines have environment-specific overrides
 * - Use globalBaselines.setEnvironment('ci') in CI pipelines
 *
 * Issues: postgres-9zvs, postgres-2paw
