PostgreSQL is an efficient open-source database management system, which has been growing in level of popularity lately as a result of its stability and reliability. It offers lots of innovative features and it may be used to keep any kind of info. PostgreSQL may be interfaced with numerous programming languages, like PHP, Python, Perl, Java, C++, Ruby, and so on. Also, it may be used for scalable apps because a single field inside a PostgreSQL database may be up to 1 Gigabyte, a table - up to 32 GB, while the database as a whole doesn't have a limit for its total size. PostgreSQL also performs swifter than other SQL control systems when complex operations are performed. Many large firms and institutions have already migrated to PostgreSQL for their websites or products - Apple, Cisco, the US State Department, the University of California, Berkeley, and others.
