windows安装瀚高数据库报错问题

错误描述：

Connection to localhost:5866 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
Connection to localhost:5866 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
    Connection refused: connect
    Connection refused: connect

查了很多都无法解决，当初还以为是本地安装的postgreSql影响到它，去停掉postgreSql还是不行；最后查到一个博主说的可能是运行内存不够导致的。[参考博客](https://blog.csdn.net/yesmldn/article/details/140039849)

解决办法：
去你安装瀚高数据目录（如：D:\highgo\database\6.0.4）搜索postgresql.conf该文件修改内存配置，原来的2048的我改为1024就可以了；最后打开任务管理器，启动hgdb-enterprise-6.0.4即可。
修改postgresql.conf

maintenance_work_mem = 1024MB #maintenance_work_mem = 64MB		# min 1MB

如果还是不行，可以试试去防火墙添加该数据库端口号。
