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.
