Well, "received fast shutdown request" would explain what is
going on. The server shuts down, and all active connections
are terminated, which on the client end looks exactly like
you described.
What is odd is that you say it is repeatable.
What could be sending SIGINT to the postmaster whenever
you try to connect? Are database server and web server
on the same machine?
Try to find out what is going on there.
How does the log look when you enable
log_connections and log_disconnections in postgresql.conf?
