How to do it...
For this recipe, we will need at least three PostgreSQL servers. For demonstration purposes, we'll assume they are named pgha1, pgha2, and pgha3. Follow these steps on all three servers:
- Debian-based systems should use the apt-get command to install as many distribution-provided packages as possible:
sudo apt-get install python3-psycopg2 python3-pip python-yaml
- Red Hat-based systems will need to substitute this yum command instead:
sudo yum install python3-psycopg2 python3-pip PyYAML
