Does creating one issue on @cloudberrydb/pljava repo make sense?

After discussion, the root cause is there is a plan diff for postgres planner and ORCA, so it's database kernel bug.

For postgres planner, javatest.transferPeople is executed at QD after gather, but for ORCA, javatest.transferPeople is executed on QE.

If add execute on master when creating function javatest.transferPeople, another error occurred.
