What rules of thumb exist for: * How often a table needs to be vacuumed? * How often a table needs to be analyzed? * How to tune Autovacuum? I have a large DB server, and I'm concerned that it's not being autovaccumed and autoanalyzed frequently enough. But I have no idea what proper values should be? A related question: If I INSERT a large number of records per day, similar in nature to the existing records, does that require new vacuum? new analyze? Or do I only need those for DELETEs or changes to the nature of records? Finally: What type of performance impact can I expect from vacuum and analyze, in general? -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
