This is fixed in the latest round of minor releases, but not in a way that
will help you if you already pg_upgrade'd such an extension:

http://git.postgresql.org/gitweb/?p=postgresql.git&a=commitdiff&h=6cead413b

Per the comments there, you could manually add that operator family back
to its extension, or just ignore the duplicate-opfamily complaints you'd
get during a restore.
