for accessing you could use

(NEW.created).by

for setting it, as far as I know  it's not possible to assign directly
to a field of a composite type in a record,
but something like this would work

# create table foo (a info_base);

# create or replace function foobartrig() returns trigger AS
$func$
declare rec info_base;
begin
rec := ('AAAAAAAAAAAAAAAAAA', (NEW.a).at);
NEW.a := rec;
raise warning '%', NEW;
RETURN NEW;
END;
$func$
language plpgsql;
CREATE FUNCTION


# insert into foobar values (('aoeu',current_timestamp)::info_base)
;
WARNING:  ("(AAAAAAAAAAAAAAAAAA,""2013-06-24 11:55:55.610049"")")


Hope this was of some help...
