I'm not excited about introducing YA cross-platform difference in our
library/linking behavior without fairly strong evidence that it's
necessary. The available evidence points in the other direction.
As for linking against an external .so, commit dddfc4cb2 just went to
some lengths to make sure that that *wouldn't* happen. But as long
as all the builds expect libpq.so to end up in the same place after
installation, I doubt it matters much what happens at build time.
You just need to control which build actually installs it.
