Hello there,
Yes, the autovacuum is set on by default on the PG 8.3.
The vacuum is not full, to run a full vacuum you need to set a cron job; better to run at the night.
I don't set autovacuum on the production databases, only in the Slony's slave machines and in the developmente machine.
For autovacuum settings you need to set and see if it's ok for you.
to see if the vacuum is running you can use the command "ps axf | grep postgres" on the linux server. Sometimes autovacuum is so fast that you even notice him.
I hope that I helped
Best Regards,
Rafael Domiciano

Hello Gurus,
I'm new to PG , running PG 8.3 on Linux and reading trough docs is mentioned that in PG vers 8.3 an AUTO vacuum process has been implemented which will run
full vacuum on all user and system tables + analyze and there is NO need fro DBA to schedule a crontab job to run this maintenance jobs . If this is true , here are my questions :
Would like to know from your experience is this automated process sufficient and reliable in a warehouse database , can I rely only on this internal process ?
How can I see when the job has been run or completed by PG ?
I have configure track_count=true, what values should I go for autovacuum_naptime from your experience?
Isabella
