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

  *	  Equality functions to compare node trees.
  *
- * NOTE: we currently support comparing all node types found in parse
- * trees.  We do not support comparing executor state trees; there
- * is no need for that, and no point in maintaining all the code that
- * would be needed.  We also do not support comparing Path trees, mainly
- * because the circular linkages between RelOptInfo and Path nodes can't
- * be handled easily in a simple depth-first traversal.
- *
  * NOTE: it is intentional that parse location fields (in nodes that have
  * one) are not compared.  This is because we want, for example, a variable
  * "x" to be considered equal() to another reference to "x" in the query.
