This is a networking setup problem, not a Postgres problem.
"ifconfig lo" might show something useful. On a functioning
Fedora box I get

$ ifconfig lo
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:1326801 errors:0 dropped:0 overruns:0 frame:0
TX packets:1326801 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:392324376 (374.1 MiB) TX bytes:392324376 (374.1 MiB)

If no joy there, try checking just what "localhost" is resolving as.

regards, tom lane

PS: I trust "locahost" above is a copy and paste error, else that's
probably your problem.
