Or something that's compiled with the server, but produces a separate
.so that's the only thing that links to LLVM. So packagers can avoid a
dependency on LLVM for postgres.
I suspect it wouldn't be worth the complexity, the added indirection
necessary, etc. If you're using packages then pulling in LLVM isn't a
big deal. If you're not, then don't use --with-llvm .
