Requesting exclusive locks on database objects whilst jogging a parallel dump could cause the dump to fail. The key reason why would be that the pg_dump chief method requests shared locks (obtain SHARE) on the objects which the worker procedures are going to dump later on in order to make certain that nobody deletes them and tends to make them go away though the dump is managing.
