 * - also used for 'sql_queries_pers1' and 'sql_queries_pers10' tests (with 'persistpoolmax=1' and
 *'persistpoolmax=10' for all servers)

 * - create t1 table and INSERT a lot of date into it
 * @verbatim
 *  INSERT INTO t1 (x1, fl) VALUES (0, 0), (1, 0), ...(15, 0);
 *  INSERT INTO t1 (x1, fl) VALUES (0, 1), (1, 1), ...(255, 1);

 *  @endverbatim
 * - check date in t1 using all Maxscale services and direct connections to backend nodes
 * - using RWSplit connections:
 *   + DROP TABLE t1
 *   + DROP DATABASE IF EXISTS test1;
 *   + CREATE DATABASE test1;
 * - execute USE test1 for all Maxscale service and backend nodes
 * - create t1 table and INSERT a lot of date into it
 * - check that 't1' exists in 'test1' DB and does not exist in 'test'
 * - executes queries with syntax error against all Maxscale services
 *   + "DROP DATABASE I EXISTS test1;"
 *   + "CREATE TABLE "
 * - check if Maxscale is alive
