I guess as long as the pgunixsocket thing is in there, it makes sense
to substitute DefaultHost for it on Windows, but are we sure that's
something to back-patch?
Right now, as I was saying, PQhost is in some gray area where it's not too
clear what its charter is. It's not "what was the host parameter", for
sure, but we haven't tried to make it an accurate description of the
connection either. It's a bit less accurate on Windows than elsewhere,
but do we want to risk breaking anything to only partially resolve that?
More generally, if we do go over in 9.4 to the position that PQhost
reports the host parameter and nothing but, I'm not sure that introducing
a third behavior into the back branches is something that anybody will
thank us for.
