PostgreSQL is a powerful open-source database control system, which has been growing in level of popularity lately on account of its stability and reliability. It comes with countless advanced functions and it may be used to keep any type of content. PostgreSQL could be interfaced with many different programming languages, like PHP, Python, Perl, Java, C++, Ruby, etc. Also, it can be used for scalable applications due to the fact that a single field inside a PostgreSQL database can be up to 1 GB, a table - up to 32 GB, while the database in general does not have a limit for its total size. PostgreSQL also works swifter than other SQL control systems when complicated operations are executed. Many big corporations and organizations have already moved to PostgreSQL for their websites or products - Apple, Cisco, the US State Department, the University of California, Berkeley, and others.
