postgresql-client 7.5.15 (amd64 binary) in ubuntu dapper

front-end programs for PostgreSQL (transitional package)
 This is a transitional package to automatically migrate to the new
 multicluster/multiversion structure provided by postgresql-common and
 postgresql-<version>. You can safely remove this package after a
 successful installation.
 .
 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.
 .
 If you install PostgreSQL on a standalone machine, you need this
 package, too. On a network, you can install this package on many
 client machines, while the postgresql-server package may be installed
 on only one machine.
 .
 PostgreSQL is an object-relational SQL database management system.
