No, but PostgreSQL's query planner may take a different approach for a small table than a large one. The statistics used are generated during VACUUM ANALYZE/VACUUM FULL operations and, under 8.1, are probably maintained by autovacuum, but you can always vacuum manually and see if that changes the query plan. -Owen ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
