3 * index_selfuncs.h
4 * Index cost estimation functions for standard index access methods.
5 *
6 *
7 * Note: this is split out of selfuncs.h mainly to avoid importing all of the
8 * planner's data structures into the non-planner parts of the index AMs.
9 * If you make it depend on anything besides access/amapi.h, that's likely
10 * a mistake.
