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.
