some people use separate scheme contrib to load all contrib stuff,
so upgrading is much easy.

from my understanding, the only function missed is the

-CREATE FUNCTION rank_cd(int4, tsvector, tsquery)
-CREATE FUNCTION rank_cd(int4, tsvector, tsquery, int4)

you need to change your application to use rank_cd()
as it described in reference manual.

-CREATE FUNCTION snb_ru_init(internal)

changed to

+CREATE FUNCTION snb_ru_init_koi8(internal)
+CREATE FUNCTION snb_ru_init_utf8(internal)

since we now support multibyte encoding (UTF-8 as well)
