I believe you need to look at it more carefully. I don't think it's
making any such assumption. Specifically, it has three loops; an "until
we're aligned" loop, then a "while we're aligned", and a "when we've
done all the aligned we could do".
On the flip side, I am curious as to if the arguments to a stored
procedure are always aligned or not. Never had a case to care before,
but if palloc() is always going to return an aligned chunk of memory
(per MemSetAligned in c.h) it makes me wonder.
Thanks,
