+  summary: PostgreSQL server and client module
+  description: PostgreSQL is an advanced Object-Relational database management
+               system (DBMS). The postgresql-server package contains the
+               programs needed to create and run a PostgreSQL server, which
+               will in turn allow you to create and maintain PostgreSQL
+               databases. The base postgresql package contains the client
+               programs that you'll need to access a PostgreSQL DBMS server.
