engines/adva_cms/db/migrate/20090709111934_add_email_notification_to_site.rb has:

add_column :sites, :email_notification, :boolean, :default => 0

Which fails under PostgreSQL:

==  AddEmailNotificationToSite: migrating =====================================
-- add_column(:sites, :email_notification, :boolean, {:default=>0})
rake aborted!
An error has occurred, this and all later migrations canceled:

PGError: ERROR:  column "email_notification" is of type boolean but default expression is of type integer
HINT:  You will need to rewrite or cast the expression.
: ALTER TABLE "sites" ALTER COLUMN "email_notification" SET DEFAULT 0

The attached patch replaces :default => 0 with :default => false
