That seems pretty sensible to me. I think we should aim for a
configuration that works by default. If we use -fPIC where -fpic
would have been better, the result is that on some platforms there
might be a speed penalty, probably small. In the reverse situation,
the build fails. I believe that the average PostgreSQL extension
developer will prefer the first situation. If somebody has got an
extension which is small enough to use -fpic and that person cares
about minimizing the performance penalty on s390 or other platforms
where they have this problem, then they can arrange an override in the
opposite direction.
