How to install pgAdmin4 on Ubuntu 19.04?

Developers should use all kinds of tools to speed up their daily work. This allows them to be more productive and thus create more and better applications. On the other hand, many of these tools are not found by default in the main repositories of the distribution and this means that we have to resort to other forms of installation. So, the benefit that these tools bring compensates the installation effort. Especially when we are manipulating application data that can be all kinds of information. That’s why, in this post, we will show you how to install pgAdmin4 on Ubuntu 19.04.

pgAdmin is the most popular and features rich Open Source administration and development platform for PostgreSQL, the most advanced Open Source database in the world.

Thanks to this application, you can have a graphical interface to manage everything related to PostgreSQL. The main advantage of this program is the ability to view all the records we have stored. On the other hand, we can create connections and customize them to achieve even more security. It is also possible to create, modify and delete databases.

So, pgAdmin4 becomes a printable application if you use a lot of PostgreSQL or if you want to use it for educational purposes.
