Indexes are updated automatically. Note: this means indexes will speed up queries, but incur a performance penalty for insert/update/delete operations. Stats (see ANALYZE) are *not* updated automatically, so if you are using those and your table stats are somewhat dynamic, you may need to re-run ANALYZE. -j -- Jay A.
