* NOTE: a general convention when copying or comparing plan nodes is
* that we ignore the executor state subnode. We do not need to look
* at it because no current uses of copyObject() or equal() need to
- * deal with already-executing plan trees. By leaving the state subnodes
+ * deal with already-executing plan trees. By leaving the state subnodes
* out, we avoid needing to write copy/compare routines for all the
* different executor state node types.
*
- * Another class of nodes not currently handled is nodes that appear
- * only in "raw" parsetrees (gram.y output not yet analyzed by the parser).
- * Perhaps some day that will need to be supported.
