 // The following table is used to store star (aka bookmark) information. This
 // class derives from URLDatabase, which has its own schema.
 //
 // starred
 //   id                 Unique identifier (primary key) for the entry.
 //   type               Type of entry, if 0 this corresponds to a URL, 1 for
 //                      a system folder, 2 for a user created folder, 3 for
-//                      other.
+//                      other, 4 for synced.
 //   url_id             ID of the url, only valid if type == 0
 //   group_id           ID of the folder, only valid if type != 0. This id comes
 //                      from the UI and is NOT the same as id.
 //   title              User assigned title.
 //   date_added         Creation date.
 //   visual_order       Visual order within parent.
 //   parent_id          Folder ID of the parent this entry is contained in, if 0
 //                      entry is not in a folder.
 //   date_modified      Time the folder was last modified. See comments in
 //                      StarredEntry::date_folder_modified
