The stacktrace seems to be from the parallel-query-leader backend.
Was there another core file?

The lack of any indication in the postmaster log that the postmaster saw
the parallel worker's crash sure looks the same as lorikeet's failure.
But if the postmaster didn't dump core, then we're still at a loss as to
why it didn't respond.
