This update of Percona Distribution for PostgreSQL includes the following fixes for Red Hat Enterprise Linux 8 / CentOS 8:

- ``llvm`` packages are added to the repository. This fixes compatibility issues with LLVM from upstream. To use ``llvm`` packages supplied by us, disable the upstream ``llvm-toolset`` module before the installation:

```
sudo dnf module disable llvm-toolset
```

- systemd unit file includes the correct path to Patroni configuration file. 
- ``etcd`` and ``python3-python-etcd`` packages are added as ``RPM`` packages to Percona Distribution for PostgreSQL for Red Hat Enterprise Linux / CentOS 8. These packages are used to set up High Availability clusters with Patroni.  For how to set up Patroni clusters, see [Patroni documentation](https://patroni.readthedocs.io/en/latest/README.html#running-configuring)
