Hi Ivan,

Sorry that I wasn't there during the meeting, otherwise I would have had
some things to say. Let me say it here if you don't mind.

I've been fighting *a lot* this week, to have nailgun to use a socket
for postgres that I created in /tmp/tmp.<something> (as one can't use
something else when building packages). The normal way would be to put
the path of that created postgres instance as hostname in
nailgun/settings.yaml, but this doesn't work, and I always ended up
having the /tmp path being passed to psycopg2 as dbname. So, because the
resulting dbname is completely wrong, I never were able to run unit
tests correctly, unless I completely bypass that, and force my own baked
DSN into psycopg2 (eg, hacking __init__.py of psycopg2 to make sure I
had what I expected).

So my question is: could someone help me to fix nailgun, so that it is
possible to use a postgres instance path as hostname? Otherwise, I'll
have no way to run unit tests at package build time.
