|
* 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.
