PostgreSQL is an effective open-source database control system, that has been growing in popularity lately because of its stability and reliability. It provides numerous advanced features and it can be used to store any sort of content. PostgreSQL may be interfaced with numerous programming languages, such as PHP, Python, Perl, Java, C++, Ruby, and so on. Additionally, it could be used for scalable applications due to the fact that 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 complicated operations are executed. Lots of major corporations and institutions have already migrated to PostgreSQL for their sites or products - Apple, Cisco, the US State Department, the University of California, Berkeley, and others.
