This looks like a copy-pasto to me, as the tuple descriptor coming
from the relation is just used for sanity checks on the attributes
depending on the options by the caller for the COPY.

The assignment of num_phys_attrs could be kept at the same place as
on HEAD, a bit closer to the palloc0() where it is used.
