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?
