# Install Percona Distribution for PostgreSQL

We recommend that you install Percona Distribution for PostgreSQL from Percona repositories using the package manager of your operating system. Find the list of supported Linux distributions on the [Percona Software and Platform Lifecycle page](https://www.percona.com/services/policies/percona-software-support-lifecycle#pgsql) page.

Installing Percona Distribution for PostgreSQL from Percona repositories means to subscribe to these repositories. Percona provides the [percona-release](https://www.percona.com/doc/percona-repo-config/index.html) repository management tool for this purpose. It simplifies operating repositories and enables to install and update both Percona Distribution for PostgreSQL packages and required dependencies smoothly.


## Package contents

In addition to individual packages for its components, Percona Distribution for PostgreSQL also includes two meta-packages: `percona-ppg-server` and `percona-ppg-server-ha`.

Using a meta-package, you can install all components it contains in one go.

### `percona-ppg-server`

=== "Package name on Debian/Ubuntu"

     `percona-ppg-server-12`

=== "Package name on RHEL/derivatives"

     `percona-ppg-server12`

The `percona-ppg-server` meta-package installs the PostgreSQL server with the following packages:

| Package contents | Description                             |  
| ---------------- | --------------------------------------- | 
| `percona-postgresql%{pgmajorversion}-server` | The PostgreSQL server package. |

The `%{pgmajorversion}` variable stands for the major version of PostgreSQL.
