/**
 *
 * update.php - automatic system update
 *
 * This function is responsible for doing post update changes to the data
 * (not the structure) in the database.
 *
 * Database structure changes are done in config/dbstructure.config.php
 *
 * If there is a need for a post process to a structure change, update this file
 * by adding a new function at the end with the number of the new DB_UPDATE_VERSION.
 *
 * The numbered script in this file has to be exactly like the DB_UPDATE_VERSION
 *
 * Example:
 * You are currently on version 4711 and you are preparing changes that demand an update script.
 *
 * 1. Create a function "update_4712()" here in the update.php
 * 2. Apply the needed structural changes in config/dbStructure.php
 * 3. Set DB_UPDATE_VERSION in config/dbstructure.config.php to 4712.
 *
 * If you need to run a script before the database update, name the function "pre_update_4712()"
