+ * Check temporary tables commands functionality (relates to bug 430)
+ *
+ * - create t1 table and put some data into it
+ * - create temporary table t1
+ * - insert different data into t1
+ * - check that SELECT FROM t1 gives data from temporary table
+ * - create other connections using all MaxScale services and check that SELECT
+ *   via these connections gives data from main t1, not temporary
+ * - dropping temporary t1
+ * - check that data from main t1 is not affected
