PostgreSQL is a powerful open-source database control system, that has been growing in popularity lately as a result of its stability and reliability. It offers a lot of sophisticated features and it can be used to keep any sort of info. PostgreSQL can be interfaced with numerous programming languages, including PHP, Python, Perl, Java, C++, Ruby, etc. Furthermore, it may be used for scalable applications because a single field in a PostgreSQL database may be up to 1 GB, a table - up to 32 GB, while the database altogether doesn't have a limit for its total size. PostgreSQL also performs more quickly than other SQL administration systems when sophisticated operations are performed. Many major firms and organizations have already switched to PostgreSQL for their Internet sites or products - Apple, Cisco, the US State Department, the University of California, Berkeley, and many others.
