Tom's "problem" is probably not a bad as he thinks. The 8k tuple size limit is a
result of the current 8k page size limit, but multiple tuples are allowed on a page.
They are just not allowed to span pages. So, there is some wasted space (as is true
for many, most, or all commercial dbs also) but it is on average only the size of
half a tuple, and can be easily predicted once the tuple sizes are known.
