pgsql: Teach the planner to support index access methods that only

Log Message: ----------- Teach the planner to support index access methods that only implement amgettuple or only implement amgetbitmap, instead of the former assumption that every AM supports both APIs. Extracted with minor editorialization from Teodor's fast-GIN-insert patch; whatever becomes of that, this seems like a simple and reasonable generalization of the index AM interface spec.
