password policy schema mismatch issue

I get the following error on the schema compare page:

column policy - difference on: default
declared: array('description' => t('TODO: please describe this field!'), 'type' => 'text', 'not null' => TRUE, 'default' => '')
actual: array('description' => t('TODO: please describe this field!'), 'type' => 'text', 'not null' => TRUE)

password_policy.policy is type text and may not have a default value
