If you significantly altered the data in a table, run `ANALYZE` or `VACUUM ANALYZE` (system catalog tables only) to update table statistics for the query optimizer. Current statistics ensure that the optimizer makes the best decisions during query planning and avoids poor performance due to inaccurate or nonexistent statistics.
