I don't plan to go to war over this, but it's not apparent to me that
PQhostaddr was such a broken concept that we should risk library
compatibility issues post-RC1.  I will grant that *probably* there are
no users of the function yet, but why do we need to take the chance?
There are plenty of other access functions just like this one in libpq.
I think the bar for deciding that we can break compatibility at this
point is a lot higher than "well, maybe this isn't very useful".
