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