I have tested the patch with REL_12_STABLE for the given error scenario by running the "CREATE TEMPORARY TABLE..." and
"DROPOWNED BY..." commands concurrently using parallel background workers. I have also tested a few related scenarios
andthe patch does seem to fix the reported bug. Ran make installcheck-world, no difference with and without patch.
