Hi,

I am checking my drupal site with schema module (http://drupal.org/project/schema) and it report one issue about validation_api schema:

validation_api_validators
o column module:
declared: array('type' => 'varchar', 'length' => 32, 'default' => )
actual: array('type' => 'varchar', 'length' => '32', 'not null' => FALSE)
o column module: key 'not null' not set, ignoring inspected default value

Maybe it issue could be important.
