Description
So I need to obtain some metrics from a database and I'm planning to create a custom collector as described here: http://prometheus.github.io/client_python/collector/custom/
I use asyncpg to connect to PostgreSQL. My problem though is that asyncpg query needs to be called from an async function and collect() is synchronous.
Is there an async equivalent? It looks like the client supports being used from ASGI.

Research direction
Start with the custom collector documentation linked in the issue and the client’s ASGI support. Trace how collect() is invoked and compare that path with asyncpg’s requirements. Done means establishing and documenting whether asynchronous collection is supported, or defining the required client behavior if it is not.
