postgresql-client 8.4.8-0ubuntu0.11.04 (i386 binary) in ubuntu natty

 This package contains client and administrative programs for
 PostgreSQL: these are the interactive terminal client psql and
 programs for creating and removing users and databases.
 .
 This package always depends on the currently supported database
 client package for PostgreSQL. If you install PostgreSQL on a
 standalone machine, you need the server package postgresql, too. On a
 network, you can install this package on many client machines, while
 the server package may be installed on only one machine.
 .
 PostgreSQL is an object-relational SQL database management system.
