ISTM that you could just do this in connectDBStart() where it actually
decides on AF_UNIX. It's just a different place to do it and you don't
have to maintain it in two different places (PQconnectdb-style and
PQsetdbLogin-style).

For symmetry PQhost() should return what was put in as host. Since you
cannot put in a unix socket as a separate connection parameter there
cannot be a function PQunixsocket to get one out. In fact, ISTM there
should not be anything that's explicitly called 'unixsocket'.

I don't like the code in fe-connect.c one bit, it's way messed up.
Evidently there's even some code in there that allows you to do this:

$ psql tcp:postgresql://localhost:5432/peter

which is certainly a cool idea, only that it ends up with

psql: connectDBStart() -- unknown hostname: J"J"@st

Eventually I think the URL-style is the way to go, especially with SSL
becoming mainline, so I'd hate to publish too many new functions of
questionable value for a feature which is not very well thought out yet.
