Module Contents
---------------

.. py:function:: suppress_pool_warnings() -> None

   Suppress connection pool warnings during cleanup.

   Suppresses event loop closure warnings that occur during normal
   connection termination. This is safe because connections are
   being cleaned up properly, just after the event loop closes.

   Call this once during application startup.

   Example:
       >>> suppress_pool_warnings()


.. py:function:: setup_pool_event_handlers(engine: sqlalchemy.ext.asyncio.AsyncEngine) -> None

   Setup event handlers for connection pool.

   Adds event listener to suppress errors during connection closure.
   This handles cleanup gracefully even if event loop is closed.

   Args:
       engine: AsyncEngine instance

   Example:
       >>> from sqlalchemy.ext.asyncio import create_async_engine
       >>> engine = create_async_engine("postgresql+asyncpg://...")
       >>> setup_pool_event_handlers(engine)
