Serializing Connection/Pool/Record objects

I'm trying to use asyncpg in combination with Dask, but I'm running into the problem that Pool, Connection or asyncpg.Record objects cannot be serialized (pickled) to and from my workers. (I need to supply a Pool or Connection to a worker, and expect Record objects back)

Any suggestions?
Regards,

No file, test, or entry point is named. First clarify whether Pool, Connection, and asyncpg.Record should support Dask serialization and what constraints apply; completion criteria and affected code paths are not defined in the issue.
