首次尝试启动 Apache Tomcat 时，ThingWorx Platform PostgreSQL 安装程序失败，并显示“无法从底层数据库获取连接”

• ThingWorx Platform PostgreSQL 安装程序验证数据库连接，但在安装后无法启动
• 由于 PostgreSQL 数据库连接问题，ThingWorx Platform 安装程序无法完成，但安装过程中已验证连接
• ThingWorx Platform 数据库表已成功创建，但安装程序因数据库连接错误而无法启动 ThingWorx Platform
• ThingWorx 平台安装程序成功连接到数据库，绕过数据库连接详细信息对话框，但在安装过程结束时失败
• 即使连接有效且已创建数据库表，ThingWorx 平台也不会开始引用数据库连接错误
• 在命令提示符或终端中通过psql连接到数据库有效，但 ThingWorx 平台仍然无法完成安装并出现数据库连接错误
• PostgreSQL 数据库与 ThingWorx Platform 安装在同一主机上，连接似乎是从不同的 IP 地址（环回、非环回）建立的，具体取决于连接的创建位置
• ThingWorx 平台安装程序在Waiting for ThingWorx Foundation..处挂起。
• ThingWorx 平台安装超时，等待 ThingWorx 可访问
