* equalfuncs.c
* Equality functions to compare node trees.
*
- * 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
- * out, we avoid needing to write copy/compare routines for all the
- * different executor state node types.
+ * 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.
*
- * Currently, in fact, equal() doesn't know how to compare Plan nodes
- * at all, let alone their executor-state subnodes. This will probably
- * need to be fixed someday, but presently there is no need to compare
- * plan trees.
+ * Currently, in fact, equal() doesn't know how to compare Plan trees
+ * either. This might need to be fixed someday.
