in our db system (for a website), i notice performance boosts after a
vacuum
full. but then, a VACUUM FULL takes 50min+ during which the db is not
really
accessible to web-users. is there another way to perform maintenance
tasks
AND leaving the db fully operable and accessible?
You're not doing regular vacuums often enough.
well, shouldn't autovacuum take care of "regular" vacuums? in addition to
autovacuum, tables with data changes are vacuumed and reindexed once a day -
still performance seems to degrade slowly until a vacuum full is
initiated... could an additional daily vacuum over the entire db (even on
tables that only get data added, never changed or removed) help?
