hi michael

what i noticed is autovacuum not working properly as it should. i had 8.1 
running with autovacuum for just 2 days or so and got warnings in pgadmin 
that my tables would need an vacuum. i've posted this behaviour some weeks 
ago to the novice list requesting more infos on how to "tweak" autovacuum 
properly - unfortunately without any respones. thats when i switched the 
nightly analyze job back on - everything runs smooth since then.

maybe it helps in your case as well?

cheers,
thomas
