After a successful simple query, the implementation invokes
Protocol.checkin/1, which switches the socket back into active mode. The{:error, %Postgrex.Error{}, protocol}branch invokedhandle_result/2directly leaving socket in passive state. Impact: a recoverable SQL error stopped asynchronous notifications delivery on a healthy connection. It would self heal on the next successful queryThis PR tries to checkin the connection on error, and if that fails disconnects.
