4779 COMMENT ON FUNCTION "delete_private_data"() IS 'Used by lf_export script. DO NOT USE on productive database, but only on a copy! This function deletes all data which should not be publicly available, and can be used to create a database dump for publication. See source code to see which data is deleted. If you need a different behaviour, copy this function and modify lf_export accordingly, to avoid data-leaks after updating.';
