Ah OK, that might be reasonable. Perhaps, then errorDuplicateDefElem()
and errorConflictingDefElem() would be better than what I originally
suggested.

BTW, another case I spotted was this:

copy (select 1) to stdout csv csv header;
ERROR:  option "format" specified more than once
LINE 1: copy (select 1) to stdout csv csv header;
                                      ^

which isn't good because there is no option called "format".
