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.
