Fwiw I think the real problem is that building static libraries
"properly" requires different compiler options -- notably they're not
normally built with -fPIC. So that means building every object twice
which kind of breaks make's build model which has a simple dependency
graph where each object appears once. Some packages do this by
inventing a foo-shared.o and foo-static.o but that introduces its own
weirdness.
I don't know what the downsides would be of creating a static library
out of objects built with -fPIC. It might just be a small performance
penalty which might be no big deal for libpq. That may be a good
compromise.
