The flag for huge allocations may be useful, but I don't actually see
much value in the flag ALLOC_NO_OOM if the stuff in aset.c returns
unconditionally NULL in case of an OOM and we let palloc complain
about an OOM when allocation returns NULL. Something I am missing
perhaps?

Yes, this would simplify the footprint of this patch to aset.c to a
minimum by changing the ereport to NULL in a couple of places.
