great for INSERT, but rather inert on UPDATE.

create table _gribnif (
    created  timestamp default current_timestamp,
    modified timestamp,
    other    text,
);

create view gribnif ...

create rule gribnif_edit as
on update to gribnif
do instead (
    update _gribnif set
        MODIFIED = CURRENT_TIMESTAMP,
        other    = NEW.other
    where
        id = NEW.id
    ;
);
