我在尝试在Render上部署Golang应用程序时遇到了一个问题。应用程序初始化数据库连接失败，并返回“连接拒绝”错误。我已经按照Render提供的部署步骤进行了操作，但无法建立到数据库的连接。
下面是我从渲染日志中得到的错误

Jul 10 02:56:40 AM  [error] failed to initialize database, got error failed to connect to `host=127.0.0.1 user=postgres database=easytickets`: dial error (dial tcp 127.0.0.1:6500: connect: connection refused)

字符串
我在Render应用 Jmeter 板中设置了环境变量，如下所示：

POSTGRES_HOST=127.0.0.1
POSTGRES_USER=postgres
POSTGRES_PASSWORD=*******
POSTGRES_DB=easytickets
POSTGRES_PORT=6500

PORT=8000
CLIENT_ORIGIN=http://localhost:3000

EMAIL_FROM=******
SMTP_HOST=*******
SMTP_USER=*********
SMTP_PASS=*********
SMTP_PORT=587
