PostgreSQL is a powerful relational database management system (rdbms) that is similar to Ingres. PostgreSQL is an enhancement of the original POSTGRES database management system, a next-generation DBMS research prototype. While PostgreSQL retains the powerful data model and rich data types of POSTGRES, it replaces the PostQuel query language with an extended subset of SQL.
