You do have the right idea, but you need to inspect the static
configuration setting the server is using as opposed to the connection
state reported by the function.
port
The TCP port the server listens on; 5432 by default. Note that the same
port number is used for all IP addresses the server listens on. This
parameter can only be set at server start.
