Environment

Here is to learn PG from scratch, in order to adapt to the trend two years later, so I choose the latest version

Redhat 7.8

PostgreSQL 12.2 source code

download

Open the PostgreSQL website https://www.postgresql.org/ and click Download on the menu bar.

You can click on the version you need according to your needs. Here, in order to better learn PG and not lag behind other big names, I choose to download the latest version of the source code.
