## Summary
<!--Explain briefly what goes wrong and explain why you believe this is a bug and not the intended behavior of SQLite (if it is not a crash).-->**No review yet**
## Minimized query
```sql
PRAGMA secure_delete = TRUE;
.stats stmt
SAVEPOINT sp4970;
.scanstats on
DROP TABLE IF EXISTS t0;
CREATE TABLE t0(c0 REAL UNIQUE);
INSERT INTO t0(c0) VALUES (0.0);
SELECT 3175546974276630385 < c0 FROM t0;
SELECT 1 FROM t0 WHERE NOT NOT /**/ (3175546974276630385 < c0) ;
ALTER TABLE t0 ADD COLUMN extra_80 DOUBLE COLLATE NOCASE;
ANALYZE t0;
REINDEX t0;
SELECT STRING_AGG(c0, '|') FROM t0;
RELEASE sp4970;
ALTER TABLE t0 ADD COLUMN extra_3988 TEXT NOT NULL DEFAULT 0;
ALTER TABLE t0 ADD COLUMN extra_7474 DOUB DEFAULT 0;
SELECT LEAD(c0, 0, 'default') OVER (ORDER BY c0 ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) FROM t0;
ALTER TABLE t0 RENAME COLUMN c0 TO c0_r7017;
```
