Etsuro Fujita f3baaf28a6 Fix rescanning of async-aware Append nodes. ... In cases where run-time pruning isn't required, the synchronous and asynchronous subplans for an async-aware Append node determined using classify_matching_subplans() should be re-used when rescanning the node, but the previous code re-determined them using that function repeatedly each time when rescanning the node, leading to incorrect results in a normal build and an Assert failure in an Assert-enabled build as that function doesn't assume that it's called repeatedly in such cases. Fix the code as mentioned above. My oversight in commit 27e1f1456. While at it, initialize async-related pointers/variables to NULL/zero explicitly in ExecInitAppend() and ExecReScanAppend(), just to be sure. (The variables would have been set to zero before we get to the latter function, but let's do so.)
