Yes that would be indeed cleaner this way. I have poked a bit at that
and finished with the attached that defines some rules to generate all
the files needed. But actually it does not seem to be enough, for
example on OSX this would fail to compile because it cannot find the
postgres binary in src/backend/postgres. Does somebody have an idea
what this is about? It seems that we have two problems here.
