Robert Haas b2ccb5f4e6 shm_mq: Fix failure to notice a dead counterparty when nowait is used. ... The shm_mq mechanism was intended to optionally notice when the process on the other end of the queue fails to attach to the queue. It does this by allowing the user to pass a BackgroundWorkerHandle; if the background worker in question is launched and dies without attaching to the queue, then we know it never will. This logic works OK in blocking mode, but when called with nowait = true we fail to notice that this has happened due to an asymmetry in the logic. Repair. Reported off-list by Rushabh Lathia. Patch by me.		2015-10-22 16:33:30 -04:00
