user-defined functions/triggers; cannot dump

I recently added a table, a function, and trigger to launch that
function upon update.

drop sequence bad_email_address_id;
create sequence bad_email_address_id;
drop table bad_email_address;
create table bad_email_address (
id integer not null default nextval('bad_email_address_id'),
email_address varchar(100) not null,
error_message varchar(100),
create_date datetime default current_timestamp(0),
last_update_date datetime
);
alter table bad_email_address add constraint bad_email_address_pk
primary key (id);
alter table bad_email_address add constraint bad_email_address_u
unique(email_address,error_message);

drop function trigger_update_bad_email_addres();
drop function trigger_update_bad_email_address();
drop function update_bad_email_address();
CREATE FUNCTION "update_bad_email_address" () RETURNS opaque AS 'begin
new.last_update_date = current_timestamp(0);
return new;
end;' LANGUAGE 'plpgsql';

DROP TRIGGER "trigger_update_bad_email_addres" ON bad_email_address;
DROP TRIGGER "update_bad_email_address" ON bad_email_address;
CREATE TRIGGER "update_bad_email_address"
BEFORE UPDATE ON "bad_email_address"
FOR EACH ROW EXECUTE PROCEDURE "update_bad_email_address" ();

First, how do I list user-defined functions?

Second, why do I get this error when I dump:

pg_dump -s dmatchingmoms pg_dump: query to obtain procedure name for
trigger "trigger_update_bad_email_addres" did not return exactly one
result
