PostgreSQL is a powerful open-source database control system, that has been growing in popularity lately because of its stability and dependability. It includes countless sophisticated functions and it could be used to store any sort of info. PostgreSQL could be interfaced with many programming languages, like PHP, Python, Perl, Java, C++, Ruby, and many others. Furthermore, it could be used for scalable applications since a single field in a PostgreSQL database may be up to 1 GB, a table - up to 32 GB, while the database altogether does not have a limit for its total size. PostgreSQL also performs more quickly than other SQL control systems when complex operations are executed. A lot of large companies and institutions have already switched to PostgreSQL for their Internet sites or products - Apple, Cisco, the US State Department, the University of California, Berkeley, and more.
