Your theory sounds correct since there is a contrib "pg_buffercache" and the error message indicates that the shared object cannot be found. The best solution would be to drop FUNCTION pg_buffercache_pages() and VIEW pg_buffercache in the original database before dumping. That way you can be sure that nothing else in the database depends on these objects. You can always reinstall the contrib if you need it.
