PostgreSQL is an open-source relational database management system (RDBMS) that has been around for over 30 years. It is known for its reliability, scalability, and performance. One of the most basic tasks that you will need to perform when working with PostgreSQL is to check the version of the software that you are using.
There are several reasons why you might need to check the PostgreSQL version. For example, you may need to ensure that you are using the latest version of the software, or you may need to troubleshoot a problem that you are experiencing.
