Vacuum
The VACUUM statement alone does nothing and is at present provided for PostgreSQL-compatibility.
The VACUUM ANALYZE statement recomputes table statistics if they have become stale due to table updates or deletions.
Examples
-- No-op
VACUUM;
-- Rebuild database statistics
VACUUM ANALYZE;
-- Rebuild statistics for the table & column
VACUUM ANALYZE memory.main.my_table(my_column);
-- Not supported
VACUUM FULL; -- error
