What is PostgreSQL?

PostgreSQL, commonly referred to as “Postgres,” is an open-source relational database management system. As with other relational databases, PostgreSQL stores data in tables made up of rows and columns. Users can define, manipulate, control, and query data using Structured Query Language, more commonly known as SQL. PostgreSQL bills itself as “the most advanced open-source relational database in the world,” and emphasizes extensibility and compliance with the SQL standard.
