Could you be more precise what the problem is?

We are using the client libraries from 7.2 with a PG server 7.1 and it works
seamless.

So I guess your problem is that you *dynamically* link with the client library
7.1 and the user has the shared client library 7.2.
If that actually is your problem there are two simple solutions:
link statically or ship the shared library 7.1 with the application.
The latter solution does not solve the libc insanity on Linux though.
