我有一个非常简单的typeorm，pg设置和脚本只是纱开发。我得到这个错误不知何故。

此问题是由postgres连接问题引起地（连接器报告一条不适当地消息）;
解决方案：检查postgres安装以及它是否正在运行

这个问题也发生在你试图连接postrgres与mysql连接字符串。更多详情here。
一个临时的解决方案是全局处理uncaughtException

process.on('uncaughtException', e => {
    console.error('An unhandled exception occurred:');
    
    if(  e.message == 'unknown message code: 4a' && e.code  == 'ERR_ASSERTION'){
      console.error( "Postgres error"); 
      // do what you want to do here  
    }
    else{  
    console.error(e);   
    process.exit (1);
      
    }
  
  });
