Using "heap_" as prefix of the function looks like the best choice to me and that's more consistent with the other functions we have already. Using "tuple" looks sensible as well so the last name you are proposing sounds like a good alternative. > At the beginning of pageinspect documentation page, we have a line > "All of these functions may be used only by superusers.".

I would still keep it as superuser-restricted, to avoid any risks with people playing with the internals of this function. pageinspect is sensitive enough. -- Michael
