I'm a postresql newbie, big time. I've been assigned the task of making
some simple changes to our dealer website. The PO Number field is the first
request, currently it excepts just 6 characters (do to the varchar(6) type).
Alvaro: how can this change be implemented? i can get to a postrgesql
command prompt.

You can also set atttypmod to 15+4 (right now it should be 6+4) to the
attribute in pg_attribute.
