list triggers ?

Hi all

yesterday, i created the following table:

create table kunden (id serial primary key, name varchar(30) not null,
adresse1 varchar(30) not null, adresse2 varchar(30), plz varchar(10) not
null, ort varchar(30) not null, legi varchar(10) not null, tel1
varchar(20), tel2 varchar(20), email varchar(60), rechnung boolean
default False not null, login varchar(10) not null, password varchar(10)
not null, abteilung integer not null, constraint kunden_abt_fk FOREIGN
key(abteilung) references kategorien );

part of the output of this command was:

NOTICE:  CREATE TABLE will create implicit trigger(s) for FOREIGN KEY
check(s)
CREATE

now, the creation is actually OK. But how do i find out which triggers
exist and what they look like ? (generically, in this case i assume it
to be some default, available fropm the docu)

Thanks,
Urs
