Обсуждение: Indexes
Hello This may sound like a trivial question, but can someone explain me the difference between the types of access methods toindexes that PGSQL supports? I understand HASH, but not the others.. if possible, can someone tell me what index is good for what type of situations? Like some index is better if you're goingto join tables, other if you will just query, etc... Thanks Aristide
