Do I have to setup replication to have clustering setup in Postgresql? Can I not have just clustering setup in two servers.

Postgresql 9.5.0
CentOS 6.7

ps- installed postgres on two nodes following below link:

While you will always be able to manually configure and deploy a PostgreSQL cluster on Droplets...

As of Feb 14, 2019, DigitalOcean's Managed Databases product allows you to create managed PostgreSQL clusters quickly via the Control Panel UI or API.

I am not a big Postgre user myself but doing a bit of searching found this. It sounds like Postgre only supports replication ( a couple types ) out of the box but there are third party utilities that allow you to create a clustered postgre environment.
