As the 7.1 code presently stands, libpq contains a compiled-in default
socketfile location, which the client code hopefully doesn't know about.
So, yes, if an old client has a dynamically linked libpq.so then
replacing the .so would bring that client into sync with a nonstandard
server.  However, the pitfalls should be obvious: independently built
clients, statically linked libraries, differing .so version numbers
to name three risk areas.
