I am not dealing with legacy tables, I am just starting a new db and
wondering whether I can set multiple primary key, in order to
eliminate the chance of duplicated data.
For example.
db = DAL('sqlite://storage.sqlite')
db.define_table('account',
Field('given_name'),
Field('surname'),
Field('phone_number'),
primarykey=['given_name','surname'])
