Обсуждение: When the last vacuum occured? It's necessary to run it now?

Hi,
 It would be great for maintainance if every object had a timestamp of
the last vaccum run on it. From time to time we're working with several
databases and I can't tell wich one needs a new vacuum.
 Another important information would be the rate of disposable data in
every table (like old and delete records) it would help was to
determine if a vacuum is required.
 Best regards, Thiago Fernandes Moesch

You could rather use autovacuum than adding timestamps to fields.
