PostgreSQL is an excellent open-source database management system, that has been growing in global recognition lately due to its stability and reliability. It includes many advanced features and it can be used to save any kind of content. PostgreSQL can be interfaced with a lot of programming languages, like PHP, Python, Perl, Java, C++, Ruby, and many others. In addition, it can be used for scalable applications as a single field inside a PostgreSQL database can be up to 1 GB, a table - up to 32 GB, while the database altogether does not have a limit for its total size.
