Yeah, I think you're right. We've probably not seen this because in
most usages the buffer is always block-aligned, but it looks possible
for tuplestore.c to get out of alignment if its concurrent write/read
feature is exercised just so. Do you want to try demonstrating the bug
with a smaller-than-normal setting of MAX_PHYSICAL_FILESIZE?
