PostgreSQL is an excellent open-source database management system, that has been growing in global recognition lately because of its stability and reliability. It includes plenty of advanced functions and it may be used to keep any kind of content. PostgreSQL may be interfaced with numerous programming languages, such as PHP, Python, Perl, Java, C++, Ruby, and so forth. Also, it can be used for scalable applications because a single field in a PostgreSQL database may be up to 1 GB, a table - up to 32 Gigabytes, while the database in general doesn't have a limit for its total size. PostgreSQL also works faster than other SQL management systems when sophisticated operations are executed. Many large businesses 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 others.
