Sorry, I was unclear. One reason is that there isn't necessarily anything to find. Certainly, when I try this out with a debugger, even the B-Tree scan doesn't have doesn't even have IndexScanDescData.parallel_scan set. It isn't actually a parallel B-Tree scan. It is a serial/non-parallel-aware index scan that is run from a parallel worker, and feeds its output into a gather merge node despite all this. -- Peter Geoghegan
