 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 is the client package for PostgreSQL 9.6. If you install
 PostgreSQL 9.6 on a standalone machine, you need the server package
 postgresql-9.6, 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.
