[web2py] Problem with DAL and Postgres

[Bernardo]

Dear all,

I am using web2py 1.91.6 and last version of Ubuntu. A model which
works perfectly using sqlite database, throws an error when using a
postgres database:

ProgrammingError: syntax error at or near "10000000000"
LINE 1: ALTER TABLE auth_user ADD password VARCHAR(10000000000);

posible bug in new DAL?

Thanks a lot for your help,
Bernardo
