Commit9d9c02ccd, which added the notion of a "run condition" for window functions, neglected to teach nodeFuncs.c to process the new field. Remarkably, that doesn't seem to have had any ill effects before we invented Var.varnullingrels, but now it can cause visible failures in join-removal scenarios. I have no faith that there's not reachable problems in v15 too, so back-patch the code change to v15 where9d9c02ccdcame in. The test case seems irrelevant to v15, though. Per bug #18277 from Zuming Jiang. Diagnosis and patch by Richard Guo. Discussion: https://postgr.es/m/18277-089ead83b329a2fd@postgresql.org
