Prompt
Design an asynchronous ETL pipeline using Python's asyncio and aiohttp to continuously fetch real-time forex exchange rates from multiple APIs. Create a scalable PostgreSQL schema that can handle high-frequency currency rate updates with microsecond precision, implementing proper indexing and partitioning strategies. Develop robust error handling for API failures, rate limiting, and ensure data integrity with atomic transactions. Include a mechanism to detect and log currency rate anomalies that deviate beyond standard market fluctuations.
