I've seen discussion here that made it sound like a REINDEX might also be required on tables with really high data churn (ie when VACUUM / VACUUM FULL are run a lot) - if you're not dropping and re-creating the indexes for better bulk load performance anyway, of course. Am I just confused, or can this sometimes be necessary? -- Craig Ringer
