Tests include: TestMigrationRollbackSafety (tests all migrations can be rolled back), TestMigrationTransactionRollback (validates transaction rollback mechanism), TestMigrationExtensionHandling (validates extension handling limitations), TestMigrationIdempotency (validates migration idempotency). Tests handle PostgreSQL limitations (extensions cannot be in transactions) and verify that migrations can be safely rolled back."
"implementation_notes":"Created PerformanceMonitor in internal/database/performance_monitor.go with slow query logging and performance metrics. Added Prometheus metrics for slow queries (veza_db_slow_queries_total, veza_db_slow_query_duration_seconds) in internal/metrics/prometheus.go.
