1 PostgreSQL is a robust, next-generation, Object-Relational DBMS (ORDBMS),
2 derived from the Berkeley Postgres database management system. While
3 PostgreSQL retains the powerful object-relational data model, rich data types
4 and easy extensibility of Postgres, it replaces the PostQuel query language
5 with an extended subset of SQL.
7 PostgreSQL is free and the complete source is available.
9 This package contains the database server programs.
