Installing PostgreSQL Client v10 on AWS Amazon Linux (EC2) AMI

You can try to run the following command on your Linux server:

sudo amazon-linux-extras install postgresql10

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.

those who see

Error: Package: pgdg-redhat-repo-42.0-4.noarch (/pgdg-redhat-repo-latest.noarch)

Requires: /etc/redhat-release

may still install step by step all dependencies and the server with:

yum install -y https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-latest-x86_64/postgresql10-libs-10.7-2PGDG.rhel7.x86_64.rpm
yum install -y https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-latest-x86_64/postgresql10-10.7-2PGDG.rhel7.x86_64.rpm
yum install -y https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-latest-x86_64/postgresql10-server-10.7-2PGDG.rhel7.x86_64.rpm

Since none of the previous answers worked for me, I'm adding a solution that let me install the postgresql10 client. We're using VERSION="2018.03" of Amazon Linux AMI in our pipelines.

Building from source:

^{Note: The link below points to postgresql 10.4, you may want to check for newer subversions}

sudo yum install -y gcc readline-devel zlib-devel
wget https://ftp.postgresql.org/pub/source/v10.4/postgresql-10.4.tar.gz
tar -xf postgresql-10.4.tar.gz
cd postgresql-10.4
./configure
make -C src/bin
sudo make -C src/bin install
make -C src/include
sudo make -C src/include install
make -C src/interfaces
sudo make -C src/interfaces install
make -C doc
sudo make -C doc install

The new package should be installed with all its executables in here: /usr/local/pgsql/bin

Now, keep in mind that commands psql, pg_dump etc. still point to the old version of the psql client. You can run with the full executable paths (/usr/local/pgsql/bin/psql) or prepend the new directory at the beginning of your $PATH so that the system will look it up first:

Edit ~/.bash_profile adding this at the end:

export PATH="/usr/local/pgsql/bin:$PATH"

Then run:

source ~/.bash_profile

Now everything should be ready:

[ec2-user@ip-xx-x-x-xxx ~]$ psql --version
psql (PostgreSQL) 10.4

Adapting Haneef Mohammed's answer for Amazon Linux 1 (tested on 2018.03):

Go to the Postgres repositories page and grab the URL for 'Red Hat Enterprise Linux 6 - x86_64'. Install the PG repos and amend the entries, replacing '$releasever' with '6.9' (or newer?):

[ec2-user ~]$ sudo yum install -y  https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-6-x86_64/pgdg-redhat10-10-2.noarch.rpm

[ec2-user ~]$ sudo sed -i "s/rhel-\$releasever-\$basearch/rhel-6.9-x86_64/g" "/etc/yum.repos.d/pgdg-10-redhat.repo"

Second part is the same:

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

As of May 25th, 2019, the following direct RPM installation worked for me on Amazon Linux 1 2018.03 (latest Beanstalk platform version) to install PostgreSQL Client 10.7:

sudo rpm -ivh --force https://yum.postgresql.org/testing/10/redhat/rhel-6-x86_64/postgresql10-libs-10.7-2PGDG.rhel6.x86_64.rpm
sudo rpm -ivh --force https://yum.postgresql.org/testing/10/redhat/rhel-6-x86_64/postgresql10-10.7-2PGDG.rhel6.x86_64.rpm
