access to the planner's cursor-related planning options, and provide new FETCH/MOVE routines that allow access to the full power of those commands. Small refactoring of planner(), pg_plan_query(), and pg_plan_queries() APIs to make it convenient to pass the planning options down from SPI. This is the core-code portion of Pavel Stehule's patch for scrollable cursor support in plpgsql; I'll review and apply the plpgsql changes separately.
