The comment next to that says that we're relying on --export-all.
If PGDLLEXPORT were being used for other contrib-module functions,
you would have a point, but AFAICS no one ever bothered.
(If this patch works, we could go around and clean up stuff like
that, but that's a bit premature at this point...)
