postgresql-8.4 8.4.7-0ubuntu0.9.10 (amd64 binary) in ubuntu karmic

 PostgreSQL is a fully featured object-relational database management
 system. It supports a large part of the SQL standard and is designed
 to be extensible by users in many aspects. Some of the features are:
 ACID transactions, foreign keys, views, sequences, subqueries,
 triggers, user-defined types and functions, outer joins, multiversion
 concurrency control. Graphical user interfaces and bindings for many
 programming languages are available as well.
 .
 This package provides the database server for PostgreSQL 8.4. Servers
 for other major release versions can be installed simultaneously and
 are coordinated by the postgresql-common package. A package providing
 ident-server is needed if you want to authenticate remote connections
 with identd.
