ticket for the remaining issue.
   
   Sorry for not following earlier, was on a full-day event yesterday.
   
   There are regressions.
   I kind of felt it's obvious from the way it works, sorry for not providing 
good examples earlier.
   
   ### Before the change
   
   ```
   > CREATE OR REPLACE TABLE t(a int) AS SELECT length(a) FROM (VALUES 
('+123')) t(a); SELECT * FROM t;
   0 row(s) fetched.
   Elapsed 0.005 seconds.
   
   +---+
   | a |
   +---+
   | 4 |
   +---+
   ```
   
   ```
   > CREATE OR REPLACE TABLE t(a int) AS SELECT length(a) FROM (VALUES 
('abcd')) t(a); SELECT * FROM t;
   0 row(s) fetched.
   Elapsed 0.078 seconds.
   
   +---+
   | a |
   +---+
   | 4 |
