localhost is plenty secure, only root can sniff it, and root can su to 
postgres and be in full ownership of your server anyways, so if you 
consider root a security risk, well, there's no cure for that.

unix domain sockets are quite secure too.   they might be slightly 
faster than tcp/ip via localhost, but its probably not enough to matter.
