+/**
+ * Update the database schema from version 2 to version 3
+ * - create the wt_gedcom_chunk table to import gedcoms in
+ * blocks of data smaller than the max_allowed_packet restriction.
+ * 
+ * The script should assume that it can be interrupted at
+ * any point, and be able to continue by re-running the script.
+ * Fatal errors, however, should be allowed to throw exceptions,
+ * which will be caught by the framework.
+ * It shouldn't do anything that might take more than a few
+ * seconds, for systems with low timeout values.
