It's entirely right: there's no such operator.
Oh, you wanted a way to write the query correctly? I think what this
person wants might be something like
select attname from pg_attribute where attnum > 0 and not attisdropped
and not exists (select 1 from pg_constraint where attnum = ANY(conkey) and conrelid = attrelid and
contype= 'p');
... although that produces quite a lot of rows, so some additional
constraint is probably wanted too.
