PostgreSQL is a flexible open-source object-relational database management system. The solution uses and extends the SQL language, combining features to store and scale complex data loads securely. This database has been maintained and improved by a large community of developers for more than 20 years.
PostgreSQL is one of the most popular database management systems. It is widely used for information integrity protection, application building, and fault-tolerant environment development. PostgreSQL users can extend it for themselves: define their own data types, indexes, languages, and the like. Apple, Instagram, Red Hat, and Fujitsu have already created products based on PostgreSQL.
