 The final panel shows the estimated monthly costs for the database. If you are happy
 that the configuration is correct, select **Create Database**.
 
+## 5. Install PostgreSQL on Ubuntu 20.04
+
+First, ensure your system is up-to-date by running the following commands:
+
+```bash
+sudo apt update
+sudo apt upgrade
+```
+
+Then, install some packages that will be needed during installation:
+
+```bash
+sudo apt install dirmngr ca-certificates software-properties-common apt-transport-https lsb-release curl -y
+```
+
+To begin installing PostgreSQL, import the GPG key to verify the installation package:
+
+```bash
+curl -fSsL https://www.postgresql.org/media/keys/ACCC4CF8.asc | gpg --dearmor | sudo tee /usr/share/keyrings/postgresql.gpg > /dev/null
+```
+
+Then, import the stable version of the PostgreSQL 15 APT repository:
+
+```bash
+echo deb [arch=amd64,arm64,ppc64el signed-by=/usr/share/keyrings/postgresql.gpg] http://apt.postgresql.org/pub/repos/apt/ $(lsb_release -cs)-pgdg main | sudo tee /etc/apt/sources.list.d/postgresql.list
+```
+
+Finally, update the repository and proceed with the PostgreSQL installation:
+
+```bash
+sudo apt update
+sudo apt install -y postgresql-client-15 postgresql-15
+```
+
+## 6. Get the database endpoint
+
+In the navigation pane of the console, select **Databases** and then
+select `gvb-database`, which we have just created. Copy the `writer`
+endpoint name (highlighted in the screenshot):
+
+{{<image filename="images/rdi/ingest/prepsrc/aurora-pgsql/GetDBEndpoint.jpg" alt="Get Database endpoint panel" >}}
+
+## 7. Connect to the database
+
+You can now connect to the Aurora PostgreSQL with the PostgreSQL client
+(installed in [step 5](#5-install-postgresql-on-ubuntu-2004)) using the
+following command. The endpoint name is the one you just copied in
+step 6 above.
+
+```bash
+psql --host=<copied-endpoint-name> --dbname=postgres --username=postgres
+```
