There is absolutely no reason to "vacumm full" unless your data-size actually are shrinking over time. (longer periods). A normal vacuum will make it available for the next run.. you most likely are running autovacuum anyway. > reindexdb Might make sense, but weekly?.. There is AFAIK a small amount of index-bloat collecting up over time in PG. But in general just "yearly" or "monthly" should really be sufficient. > Usually I purge one or two backup volumes and the above commands run in less > than 20 minutes. > > Before my monthly Full backup I delete large amount of data from the database > as I > delete one month worth of Full and Incremental backups.

No not really VACUUM FULL i telling PG to reorder the data on-disk and free up space for the os, that is a "hard task". But it is also not needed, since you are going to used it within the next week/month anyway.. so ordinary VACUUM is sufficient. > My database is about 9GB. > > If I backup database using pgdump and then restore it, will it do the same > thing as vacuumdb and reindexdb commands?
