Thread: The need for full vacuum / reindex

By occation, we dropped the whole production database and refreshed it from
a database backup - and all our performance problems seems to have gone.  I
suppose this means that to keep the database efficient, one eventually does
have to do reindexing and/or full vacuum from time to time?

Normally you only need to do that if you didn't vacuum often enough or with
high enough fsm setting and bloat has gotten out of hand to the point that
you need to recover some space.
