I have a 3 server cluster with slow replication currently. I believe it is because a very large transaction ( > 1,000,000 rows) yielded a low of dead tuples in the slony log tables. I see a lot index bloat in the slony tables - sl_seqlog has a index_ratio of 68.65, for example. sl_confirm is 78. 

Could I run 

cluster sl_seqlog using sl_seqlog;

and help this situation?
