postgresql-client 8.3.18-0ubuntu0.8.04 (i386 binary) in ubuntu hardy

 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 latest available 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.
