无法指定多个数据库连接以执行测试。

您现在可以使用多个数据库解析器来验证脚本语法，然后依次在多个数据库连接中执行脚本。

You can now validate the syntax in scripts with multiple database parsers, and run scripts serially against multiple database connections.

更有甚者，如果多个数据库连接单例被创建，客户端将会得到一个“多个数据库连接”的异常。

Additionally, if several instances of a database-connection singleton are created, you might start receiving SQLExceptions complaining about "too many database connections."
