-Must be a coderef, returing a hashref with the custom column informations.
+Hook for adding extra attributes to the

-Example:
+Must be a coderef that returns a hashref with the extra attributes.

+This attribute can also be used to set C<inflate_datetime> on a non-datetime
+column so it also receives the L</datetime_timezone> and/or L</datetime_locale>.
