Well, in that case they did a really crappy job of applying that policy to
their Postgres packages, because it sure sounds like there's still some
-fpic switches laying about in their builds.  But in any case, that
seems to me like a pretty brain-dead policy (hint: if you need -fPIC,
you'll get build failures that tell you so), so I feel no need to adopt
it for standard Postgres builds.
