This is a kernel-level refusal: your connection request never got to the
postmaster at all, ergo the contents of pg_hba.conf etc are irrelevant.
Assuming you did start the postmaster with tcpip_socket enabled, the
only other possibility I know of is that the kernel is refusing the
connection because of packet filtering rules. Check your firewall
setup and see what sort of restrictions are imposed on localhost
connections. You at least want to allow traffic to/from port 5432,
and may want to loosen it up more while you are at it.
