+Add or remove PostgreSQL databases from a remote host.

+The default authentication assumes that you are either logging in as or
+sudo'ing to the postgres account on the host.

+This module uses psycopg2, a Python PostgreSQL database adapter. You must
+ensure that psycopg2 is installed on the host before using this module. If
+the remote host is the PostgreSQL server (which is the default case), then
+PostgreSQL must also be installed on the remote host. For Ubuntu-based systems,
+install the postgresql, libpq-dev, and python-psycopg2 packages on the remote
+host before using this module.
