Yes, but you may need a way to ensure that the query canceled is the
same one that you really want to cancel. (imagine come connection
pooling and bad luck mixed together so that the long running query
actually ends but another query fires up between the time you lookup the
long running query and the time you issue the kill...). maybe
transaction id as well as pid for arguments?
