A Relational Database is a database that offers access to related data points and the one that is dependent on one another. As the name suggests relational databases are based on the relational model of representing data in a table.
There are multiple relational databases that can be used depending on your requirement and the developer's preference to develop an app like Instagram.
Based on my experience I would suggest you use MySQL or PostgreSQL rational database for developing an app like Instagram
