I am sorry to see there is no one to answer my question!

I think it is the answer to the question. From enterprise DB

pg_autovacuum is no more available in PostgreSQL 8.4. i.e you no longer need to insert into the pg_autovacuum catalog to change per-table settings for autovacuum

Now in 8.4, you can set autovacuum table configuration with ALTER TABLE / SET comman
Please use the latest pgAdmin3, which comes as a part of installation of PostgreSQL 8.4 installation.
