   5  *
   6  * NOTE: we currently support copying all node types found in parse and
   7  * plan trees.  We do not support copying executor state trees; there
   8  * is no need for that, and no point in maintaining all the code that
   9  * would be needed.  We also do not support copying Path trees, mainly
  10  * because the circular linkages between RelOptInfo and Path nodes can't
  11  * be handled easily in a simple depth-first traversal.
