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?
