Well, if it's just checking that the list matches, then maybe
CHECK_HEADER would do.
In your original proposal, I was rather wondering what should happen if
the incoming file didn't have the same set of columns called out in the
COPY command's column list. (That is, while *rearranging* the columns
might be thought non-astonishing, I'm less convinced about a copy
operation that inserts or defaults columns differently from what the
command said should happen.) If we're just checking for a match, that
question goes away.
