<productname>Postgres</productname>,
developed originally in the UC Berkeley Computer Science Department,
pioneered many of the object-relational concepts
now becoming available in some commercial databases.
It provides SQL92/SQL3 language support,
transaction integrity, and type extensibility.
<productname>PostgreSQL</productname> is an
open-source descendant of this original Berkeley code.
