Databases often have standard columns. Examples of such standard columns can be id, modified_date, created_by or row_version.

           where column_name = 'last_update') c
                    on c.table_name = t.table_name 
                    and c.table_schema = t.table_schema
where c.table_name is null 
      and t.table_schema not in ('information_schema', 'pg_catalog')
      and t.table_type = 'BASE TABLE'
