Question

我想在myoku上运行我的postgres数据库上的数据表。我可以查看我的表throw view.php，它包含在同一台服务器中。但是当我尝试连接pg数据库时抛出c＃，它给了我error.i认识到主机出错是我的IP地址。谷歌搜索后我发现我需要编辑hba.pba file.i已经安装了psql（shell）终端并且我尝试命令SHOW hba_file。但是它说必须是超级用户来检查＆＃34; hba_file＆＃34;有人可以帮助我解决我的问题

关键点在于：

Message=FATAL: 28000: no pg_hba.conf entry for host "61.642.163.26", user "fharmfggzvbzn", database "df4a8lse4537sb"， SSL关闭

您必须申请SSL连接。 Heroku不允许非SSL连接。请参阅the nPgSQL documentation for how to request an SSL connection。

你无法在Heroku上编辑pg_hba.conf，它是一个托管的PostgreSQL安装，你无法完全控制（但作为交换，你不必管理它）。

无法连接在heroku上运行的postgres数据库
