+ * index_selfuncs.h
+ *	  Index cost estimation functions for standard index access methods.
+ *
+ *
+ * Note: this is split out of selfuncs.h mainly to avoid importing all of the
+ * planner's data structures into the non-planner parts of the index AMs.
+ * If you make it depend on anything besides access/amapi.h, that's likely
+ * a mistake.
