+# PostgreSQL on Ubuntu
+
+These are Ubuntu instructions. They may vary on Windows and Mac.
+
+## Install Ubuntu
+
+Installation instructions:
+https://www.postgresql.org/download/linux/ubuntu/
+
+The simplest approach probably will not install the latest version:
+~~~
+apt install postgresql
+~~~
+
+To install the latest one, follow the instructions of "manually configure the Apt repository".
+
+## Changing the Password
+
+~~~
+sudo -u postgres psql -c "ALTER USER postgres PASSWORD 'postgres';"
+~~~
+
+## Server Management
+
+The three following commands start, stop, and show the status of the server at Ubuntu, respectively:
+
+~~~
+sudo systemctl start postgresql
+sudo systemctl stop postgresql
+sudo systemctl status postgresql
+~~~
+
+Reference: https://tableplus.com/blog/2018/10/how-to-start-stop-restart-postgresql-server.html
+
+## Repository Location
+
+To change the database location at Ubuntu:
