Ensure the file permissions mask is correct

中级别 1人工审核postgres

说明

Files are always created using a default set of permissions. File permissions can be restricted by applying a permissions mask called the umask. The postgres user account should use a umask of 0077 to deny file access to all user accounts except the owner.

As root run su - postgres -c umask. The umask must be 0077 or more restrictive for the postgres user (check .bash_profile, .profile and .bashrc of the postgres home); otherwise this is a fail.

修复方法: 操作指南或基础设施补丁

As postgres add 'umask 077' to the profile file in use (e.g. ~postgres/.bash_profile) and re-login to confirm umask prints 0077.
