Could hstore_plpython and plpython somehow have been built with different
ideas about PY_MAJOR_VERSION?  PLyUnicode_FromStringAndSize is
conditionally compiled, and the reference to it from hstore_plpython
depends on a conditionally-defined macro, and this error would make plenty
of sense if those conditions somehow diverged.  So I'd look for instance
at whether identical -I paths were used in both parts of the build.
