If so, I claim RPM is broken.

The whole point of major/minor version numbering for .so's is that
a minor version bump is supposed to be binary-upward-compatible.
If the RPM stuff has arbitrarily decided that it won't honor that
definition, why do we bother with multiple numbers at all?

To answer your question, there are no pending changes in libpq that
would mandate a major version bump (ie, nothing binary-incompatible,
AFAIK). We could ship it with the exact same version number, but then
how are people to tell whether they have a 7.0 or 7.1 libpq?
