## Minimized query

```sql
PRAGMA temp_store = 'MEMORY';
PRAGMA read_uncommitted;
PRAGMA user_version = -1.0;
.stats stmt
CREATE TABLE t1(a INTEGER PRIMARY KEY, b);
CREATE VIRTUAL TABLE t2 USING rtree(id,x0,x1);
INSERT INTO t1 VALUES(1,'apple'),(2,'fig'),(3,'pear');
INSERT INTO t2 VALUES(1,1.0,2.0),(2,2.0,3.0),(3,1.5,3.5);
CREATE TRIGGER r1 AFTER UPDATE ON t1 BEGIN
  DELETE FROM t2 WHERE id = OLD.a;
END;
ALTER TABLE t1 RENAME TO t3;
UPDATE t3 SET b='peach' WHERE a=2;
