As JD surely understands, it pains me a lot but I have to agree with him
here.

There are also a non-trivial number of organizations that just don't allow
compilers on production boxes, adding another hurdle for those. We may
think that's ridiculous, and it may be, but it's reality.

That said, I agree that a guc is probably a bad idea. I like the idea of an
environment variable if we need it to be changeable. Or perhaps what we
need is just better documentation of what's there already. Perhaps the
documentation should have a section specifically aimed at packagers?
