我正在设置一个连接到多个数据库的节点应用程序。我正在使用Map为我的所有数据库创建池，例如：

const stnPool = new Map();
async function getOtherDb(stnName){
   if(!stnPool.has(stnName)){
    stnPool.set(stnName,  new Pool({
      host: 'localhost',
      database: stnName.toLowerCase(),
      user: USERNAME,
      password: PASSWORD,
      port: 5432,
      max: 2000,
      idleTimeoutMillis: 0,
      connectionTimeoutMillis: 0,
    }))
   }
   return stnPool.get(stnName);
}

postgresql目前有10个“站点”数据库。我有10台远程服务器连接到我的服务器，每3秒钟上传一次数据。我还有x个客户端，可以连接以实时查看上传的数据。bot服务器和客户端连接通过WebSocket连接到上载/请求数据。
要建立aan查询池连接，请执行以下操作：

var uvDb = await db.getOtherDb("wx_uv")

if( uvDb != -1 ) {
    const dbT = await uvDb.connect()
    ... do various db queries ...
    dbT.release()
}

在获取服务器上载和客户端请求数小时后，我收到以下错误：

/.../node/node_modules/pg-protocol/dist/parser.js:287
const message = name === 'notice' ? new messages_1.NoticeMessage(length, messageValue) : new messages_1.DatabaseError(messageValue, length, name);
^

}

有人知道这是什么原因吗？
======更新=====尝试添加尝试/捕获以释放连接：

if( uvDb != -1 ) {
    const dbT = await uvDb.connect()
    try{
        ... do various db queries ...
        dbT.release()
    } catch (err) {
        dbT.release()
    }
}

但现在我有其他错误。。。
“错误：与并行工作程序的连接中断”
“错误：并行工作程序未能初始化”
