 to 0 disables the use of parallel workers by utility
         commands.

         Note that parallel utility commands should not consume
         substantially more memory than equivalent non-parallel
         operations.  This strategy differs from that of parallel
         query, where resource limits generally apply per worker
         process.  Parallel utility commands treat the resource limit
