Need some help: attlen is pg_attributes gives a negative value.. .

I have a table defined as:

create table contacts (
c_name char (20),
c_title char (30),
c_phone char (13),
c_ext char (5),
c_email char (60),
c_sort char (5)
);

when I query the catalog to get the field length for auto generating HTML
forms I get:

attnum|attname|typname|attlen
------+-------+-------+------
1|c_name |bpchar | -1
2|c_title|bpchar | -1
3|c_phone|bpchar | -1
4|c_ext |bpchar | -1
5|c_email|bpchar | -1
6|c_sort |bpchar | -1
(6 rows)

I know in previous versions the length as defined in the create table
statement was given. Any ideas?
