How to install PostgreSQL 13 on Ubuntu 22.04 LTS Linux
Postgres is a platform-independent object-relational database management system (ORDBMS). In many Linux distributions, the database management system is part of the basic equipment. It can also be used on Windows and macOS systems. Due to the object relationality, the DBMS is suitable for data warehouse databases. It differs from relational database management systems such as MySQL in that even complex data objects can be stored relationally in the database. Postgres works on the client-server model. The server is responsible for managing the databases and processing and answering client requests.
In addition to the server and a command line-based client, many Linux distributions also supply a client program with a graphical user interface.
