我曾尝试手动更改文件上的设置，它告诉我是错误的原因，以便它只有root访问权限，无济于事。有没有人有任何建议，以什么可能是一个好主意，让它的工作？

在此先感谢。

'chown postgres/etc /ssl/private/ssl-cert-snakeoil.key; chmod 640/etc/ssl/private/ssl-cert-snakeoil.key'（根据该消息，拥有者root也可以工作;而恕我直言，文件模式400或440 – joop

这个工作很完美，非常感谢 –

如果其他应用程序使用相同的证书，则需要'{root，440}'表单（并且PG需要位于其组中）如果只有postgres使用证书“{postgres，400}”将是最安全的（我不期望在这种情况下需要组访问） – joop

用户Joop真的很轻松地回答了这个问题。我为此感谢他。这是他的答案。

chown postgres /etc/ssl/private/ssl-cert-snakeoil.key; chmod 640 /etc/ssl/private/ssl-cert-snakeoil.key（根据邮件，所有者root也可以工作;而恕我直言，文件模式400或440会更好一些。）
