PostgreSQL is an efficient open-source database administration system, that has been growing in global recognition lately as a result of its stability and reliability. It provides many advanced functions and it may be used to store any sort of information. PostgreSQL can be interfaced with numerous programming languages, like PHP, Python, Perl, Java, C++, Ruby, and so forth. Also, it could be used for scalable applications as a single field inside a PostgreSQL database may be up to 1 GB, a table - up to 32 GB, while the database altogether does not have a limit for its total size. PostgreSQL also operates faster than other SQL management systems when sophisticated operations are carried out. Many big businesses and institutions have already switched to PostgreSQL for their Internet sites or products - Apple, Cisco, the US State Department, the University of California, Berkeley, and many more.
