I think the important question is will we eventually get the option to
do "CREATE TABLE ... STORAGE indexorg" (or whatever name) rather than
are we already getting that feature, and I think the answer is clearly
yes, so we should keep using the word "heap" in the name as the primary
feature of the historical implementation.
The "zheap" name makes it clear that it is still a heap; the main
difference (if I understand correctly) is how does tuple
updating/deletion work.
The current heap implementation is for "non-overwriting storage
management", but that's a mouthful and acronyms based on
"non-overwriting" don't seem great ("noheap" seems a bit silly. Maybe
"nowheap" is better? How about "nosheap"?)
Maybe we can take the easy way and use something like "stdheap".
Or just "nheap".
