If you want to access it on the Raspberry Pi itself, you can just install it with apt: sudo apt install pgadmin3

The psql command-line tool is fine for simple queries, and you'll find many power users stick with it for speed (and because they don't need the assistance the GUI gives), but midlevel users may find pgAdmin a more approachable way to learn and do more with a database.Īnother useful thing about pgAdmin is that you can either use it directly on the Pi or on another computer that's remotely connected to the database on the Pi. PgAdmin is a full-featured PostgreSQL GUI that allows you to create and manage databases and users, create and modify tables, write and execute queries, and browse results in a more familiar view, similar to a spreadsheet. You might find it useful to use a graphical tool to access the database. test=> select name from people where company = 'Red Hat' Open a terminal window and run the following command while connected to the internet: sudo apt install postgresql libpq-dev postgresql-client To get started, you'll need to install Postgres and some other packages.

It's fairly simple to set up a database for basic CRUD (create, record, update, delete) applications, which is a common pattern, and it is useful in many projects. A well-designed database can be efficient at looking up data in large datasets, and you won't have to worry about how it looks, just what you want it to find. You can write data in one session and it'll be there the next time you want to look. Databases are a great way to add data persistence to your project or application.
