broken link to "SELinux guide" from sepgsql

Hello,

on https://www.postgresql.org/docs/current/sepgsql.html
the "SELinux User's and Administrator's Guide" link to 
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/SELinux_Users_and_Administrators_Guide/
is broken, leads to 404.

Proper URI would be, apparently,

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/selinux_users_and_administrators_guide/index
