You only need to connect once, then use the connection handle for subsequent
database operations. If you have already made a connection by including your
connection script, there is no need to do it again. It won't hurt (other than
speed & memory), but isn't any point. Just miss out the connection in the
example code I sent. You still might want to change your connection script to
give you feedback on errors by including pg_last_error().
