Now I know why I did not get tableoid & friends: because I am querying
a view which does not yield these fields. But to be on the save side,
the clause should be added. So the complete plpgsql code example looks
like this now (in cleaner format):

EXECUTE
 'SELECT '
 || SELECT array_to_string(ARRAY(
   SELECT a.attname
     FROM pg_class c, pg_namespace nc, pg_attribute a
    WHERE nc.oid = c.relnamespace
      AND a.attrelid = c.oid
      AND a.attnum >= 1
      AND nc.nspname = 'myschema'
      AND c.relname = 'mytbl'
      AND a.attname <> 'bad_field'
    ORDER by a.attnum), ', ')
  || ' FROM myschema.mytbl';

Regards
Erwin
