yeah -- as long as you stick with v3 protocol supporting libpq (7.4+)
you should be ok.  all of the stuff that can change (binary wire
format, integer/float date time) is abstracted out of libpq itself and
is up to the application to handle.  note, some features  have been
added to libpq of course, but those are checked at link time with your
application.
