Undefined symbols for architecture x86_64:

I'm guessing this is because PL/PgSQL is a shared library and not in core?
  Is there a way around this?


yes, PLpgSQL is not referenced and, if I remember well, clang is too
restrictive.

probably

or you can add a reference on plpgsql to your Makefile

That seems unbelievably ugly, but worse, loading the library in shared_preload_libraries doesn't work:

14782 FATAL: could not load library "/usr/local/pgsql/lib/plpgtest.so": dlopen(/usr/local/pgsql/lib/plpgtest.so, 10): Symbol not found: _plpgsql_register_plugin
          Referenced from: /usr/local/pgsql/lib/plpgtest.so
          Expected in: flat namespace
         in /usr/local/pgsql/lib/plpgtest.so

I even tried putting plpgsql.so before it in the list, but no go.
