Right, it is. libpq4 == libpq3 with a few symbols removed that were
not actually intended to be used. I. e. you can use both libraries to
connect to servers from 7.3.something to 8.0 (and probably even later
versions). However, the idea is to always use the newest version and
to fade out the usage of libpq3.
