Could you call it as PQlibVersion() or even PQversion() instead of PQlibpqVersion() ?

*library* version. ÂPQserverVersion() is something else altogether,
and I wouldn't want to assume that pg_config exactly matches the library
you're linked to --- if it's even present at all.
We could add a PQlibpqVersion(), maybe, but it would be many years
before client code could rely on that being present.
