I'm possibly confused, but I thought that the design of parallel query involved an expectation that workers didn't need to get their own locks. What we've determined so far in this thread is that workers *do* get their own locks (or did before yesterday), but I'd been supposing that that was accidental not intentional. In any case, I definitely intend that they will be getting their own locks again after the dust has settled. Panic not. regards, tom lane
