Research direction

Start by reviewing asyncpg's existing LISTEN/NOTIFY handling, then compare the aiopg usage example and psycopg connection.poll documentation linked in the issue. Done means clients can receive new server notifications without issuing a dummy SELECT 1 query each time.

Written by the indexing model from the issue text.

Description

Currently, you have to execute a dummy query like SELECT 1 every time you want to get a hold of new notifications from the server. Can anything similar to aiopg be implemented in asyncpg?
