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
