I have tried to install

Answer 1

Packages/Repos which is designed to work of RedHat will work on Amazon Linux also, Amazon Linux is a minimal-install version of RHEL. You may run into compatibility issues if you select old version of Amazon Linux (Amazon linux 1) for the below steps, otherwise it should work fine in the latest version Amazon Linux 2.

Check Amazon Linux version

[ec2-user ~]$ cat /etc/system-release
Amazon Linux release 2.0 (2017.12) LTS Release Candidate

Install RHEL 7 yum repo for PostgreSQL

[ec2-user ~]$ sudo yum install -y  https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7-x86_64/pgdg-redhat10-10-2.noarch.rpm

[ec2-user ~]$ sudo sed -i "s/rhel-\$releasever-\$basearch/rhel-latest-x86_64/g" "/etc/yum.repos.d/pgdg-10-redhat.repo"

Install PostgreSQL Client v10

[ec2-user ~]$ sudo yum install -y postgresql10
[ec2-user ~]$ psql --version
psql (PostgreSQL) 10.3

Note! Amazon Linux 2 provides additional package installation through Amazon Linux Extras Repository (amazon-linux-extras) ((client only)). Since postgresql10 is not yet available, adding extra yum repo is the only solution per today.
