Right. What's actually happening in this case is that you ask the remote
side to resolve "pgsql.localhost.localdomain" for you, and the first few
people probably tell you "gosh, I have no idea", and then you hit upon a
Tor server with a busted resolver. That is, it resolves every hostname
it doesn't recognize to 127.0.0.1. Then it probably sends back a "but
my exit policy doesn't let me get to that" message. Your Tor client,
now equipped with the correct IP address for this hostname, then looks
through its directory for a Tor server that allows exit to 127.0.0.1:80,
and makes its next circuit exit from that server.

Hey, these folks opened *:80 on their servers. They get warns when they
start Tor, if they didn't explicitly ask to accept 127.0.0.1:80.
In all cases I've seen so far, you can get exactly the same page by
going to port 80 of their public IP address. So I'm not too worried.
There's a todo item on tor.eff.org/volunteer.html which asks if anybody
wants to track down what is causing the "I think I'll resolve everything
to localhost" bug. I presume it's default behavior on some broken OS
out there, likely Win32 or OS X. Anybody?
