psql installation on linux requires systemd

Question

I am installing psql on my AWS EMR (EC2 instance) which is Amazon Linux (not Amazon Linux 2).

I am getting an error after running the command

sudo yum install -y postgresql10

Error: Package: postgresql10-10.7-2PGDG.rhel7.x86_64 (pgdg10)
           Requires: systemd

Amazon Linux 2 comes with systemd but AWS EMR doesn't support Amazon Linux 2.

How can I install psql client on AWS EMR?

You can't install these packages on Amazon Linux or on Amazon Linux 2. They are designed and built for CentOS/RHEL 7. Use those distributions instead.

Amazon Linux 2 contains these packages by default. In Amazon Linux AMI these can't be installed. – Muhammad Imran Tariq Mar 15 '19 at 16:12
It doesn't guaranteed to work on Amazon Linux 2 either. If it does work, it's accidental and will break in future. – Michael Hampton Mar 15 '19 at 16:13
It worked and I checked it too – Muhammad Imran Tariq Mar 15 '19 at 18:10
Maybe it works today. But it cannot be guaranteed to work next week or next month. Then you will be stuck with a broken database after you've already gone into production. – Michael Hampton Mar 15 '19 at 18:23
