Recommend dba maintenance tasks on a regular bases

Hello,

We are currently using Postgresql 8.3.3 on Red Hat 4 and our largest database
is around 8454 MB.

I have recommend the below to my group but not sure if reindexing should be
involved since autovacuum is on?

How can I be sure auto vacumming is working fine? We haven't had any problems
plus I do a query and it does list all the tables and shows the last update
of auto vacuum and auto analyze. Is that it?

1- pg_dump - binary dump every midday and nightly
2 - auto vacuum
autovacuum = on
log_autovacuum_min_duration = 0
autovacuum_max_workers = 3
autovacuum_naptime = 1min
autovacuum_vacuum_threshold = 50
autovacuum_vacuum_scale_factor = 0.2
autovacuum_analyze_scale_factor = 0.1
3- rotate data logs
