Обсуждение: vacuum full...
I am running "vacuum full" via a shell script for a list of large databases now... and I may run out of my scheduled system down time....
If I don't finish all databases and kill the script in the middle... am I going to cause any table corruptions since "vacuum full" is rebuilding the tables and indexes....
thanks,
Jessica

No. But may I ask why you are running vacuum full? Is it a regular thing. Do all your tables in all your dbs actually need it?
I used to run vacuum full in one of my bases, but now i'm not running anymore vacuum full, just vacuum analyze in the past 1 month, but the number of necessary pages is increasing every day, now it's in 311264... there is any problem this get increasing?
When I runned Reindex few days ago, this number get not decreased.
I now that vacuum full reorders the relation, but it's the only thing that it does?
Thnks,

Same question I had for the other poster, why are you not running autovacuum? Has it proven itself not up to the task?
I don't have too much delete and update in the middle of the day to run autovacuum, but in the night, before vacuum analyze, there is some proccess that does delete and update, then run vacuum analyze.

autovacuum? Has it proven itself not up to the task?
