This script is not functional. Please run SMW_refreshData.php instead.
You can also do this to initialise SQLStore3 while still using SQLStore2:
* first run "php SMW_refreshData.php -b SMWSQLStore3 -fp" to recreate tables and initialise property pages,
* then run "php SMW_refreshData.php -b SMWSQLStore3" again to refresh all normal pages.
