1. If install as non-root user ec2-user without using sudo the install will succeed. Both EM and Postgres software will be owned by user ec2-user
2. To successfully install with sudo/root:
a. Temporarily create a dummy file /etc/redhat-release with single line for a supported RHEL version e.g.
Red Hat Enterprise Linux Server release 6.5 (Santiago)
b. Also if ec2-user will not own the EM or Postgres install directories also need to pre-create those with sudo and required permissions drwxrwxrwx before running the installer e.g.
sudo mkdir /opt/PostgreSQL-9.6.2
sudo chmod 777 /opt/PostgreSQL-9.6.2
