----
-
-## Prerequisites
-
-Before you begin the installation process:
-
-- Set up the EDB repository.
-
-  !!! Note
-  Rather than use the EDB repository, you can obtain PostgreSQL installers and installation packages from the [PostgreSQL community downloads page](https://www.postgresql.org/download/).
-  !!!
-
-  Setting up the repository is a one-time task. If you have already set up your repository, you don't need to perform this step.
-
-  To determine if your repository exists, enter this command:
-
-  `apt-cache search enterprisedb`
-
-  If no output is generated, the repository isn't installed.
-
-  To set up the EDB repository:
-
-  1. Go to [EDB repositories](https://www.enterprisedb.com/repos-downloads).
-
-  1. Select the button that provides access to the EDB repository.
-
-  1. Select the platform and software that you want to download.
-
-  1. Follow the instructions for setting up the EDB repository.
-
-## Install the package
-
-```shell
-sudo apt-get -y install postgresql-<xx>
-```
-
-Where `<xx>` is the version of PostgreSQL you are installing. For example, if you are installing version 16, the package name would be `postgresql-16`.
