When I looked at this, I thought it would be better to send the command
through the parallel slot machinery so that failures would use the same
code path as the rest of the VACUUM commands. However, you also need to
adjust ParallelSlotsWaitCompletion() to mark the slots as idle so that the
slot array can be reused after it is called.
