PostgreSQL is an efficient open-source database control system, which has been growing in level of popularity lately due to its stability and reliability. It provides many innovative functions and it could be used to save any type of content. PostgreSQL could be interfaced with a lot of programming languages, like PHP, Python, Perl, Java, C++, Ruby, and so forth. Additionally, it can be used for scalable apps due to the fact that a single field in a PostgreSQL database could be up to 1 GB, a table - up to 32 GB, while the database in general doesn't have a limit for its total size. PostgreSQL also functions faster than other SQL management systems when complicated operations are executed. Many large corporations and institutions have already moved to PostgreSQL for their websites or products - Apple, Cisco, the US State Department, the University of California, Berkeley, and many more.
