+SUMMARY = "PostgreSQL is a powerful, open source relational database system."
+DESCRIPTION = "\
+    PostgreSQL is an advanced Object-Relational database management system \
+    (DBMS) that supports almost all SQL constructs (including \
+    transactions, subselects and user-defined types and functions). The \
+    postgresql package includes the client programs and libraries that \
+    you'll need to access a PostgreSQL DBMS server.  These PostgreSQL \
+    client programs are programs that directly manipulate the internal \
+    structure of PostgreSQL databases on a PostgreSQL server. These client \
+    programs can be located on the same machine with the PostgreSQL \
+    server, or may be on a remote machine which accesses a PostgreSQL \
+    server over a network connection. This package contains the docs \
+    in HTML for the whole package, as well as command-line utilities for \
+    managing PostgreSQL databases on a PostgreSQL server. \
+     \
+    If you want to manipulate a PostgreSQL database on a local or remote \
+    PostgreSQL server, you need this package. You also need to install \
+    this package if you're installing the postgresql-server package. \
