  Thanks for reporting the diffs. The reason for failures is that
still decoding for tuple is not done as mentioned in Notes section in
mail  (http://www.postgresql.org/message-id/CAA4eK1JeUbY16uwrDA2TaBkk+rLRL3Giyyqy1mVh_6CThmDR8w@mail.gmail.com)
  However, to keep the sanity of patch, I will do that and post an
updated patch, but I think the main idea behind new approach at this  point is to get feedback on if such an
optimizationis acceptable
 
for worst case scenarios and if not whether we can get this done  with table level or GUC option.
