PostgreSQL is an excellent open-source database control system, that has been growing in popularity lately because of its stability and reliability. It provides plenty of sophisticated functions and it could be used to save any kind of info. PostgreSQL may be interfaced with lots of programming languages, like PHP, Python, Perl, Java, C++, Ruby, and so on. Also, it may be used for scalable apps because a single field in a PostgreSQL database can be up to 1 GB, a table - up to 32 Gigabytes, while the database as a whole doesn't have a limit for its total size. PostgreSQL also works swifter than other SQL administration systems when complex operations are performed. A lot of major companies and organizations have already migrated to PostgreSQL for their websites or products - Apple, Cisco, the US State Department, the University of California, Berkeley, and more.
