Yes.
If FooApp is compiled against 8.0, it will then be unable to run if you
upgrade libpq to 8.1. IIRC on Unix it will "fall forward" to the new
version if it's just a minor version upgrade (correct me if I'm wrong).
On windows, it will break with an ugly dialog box. Which is why DLL
renames are usually only done for backwards incompatible changes.
