 Description  « Hide
There is user reports that in some cases they can't kill connections. Memory dumps shows that such connection executed external query
and waits for responce from remote side. There is a suspicion that network between local and remote servers could be a reason.
Currently, when local connection is about to be killed, it send cancellation request to the remote side (if external query it executed, of course).
It seems that it could be not enough in some cases.
