   I'm a little confused by the intent of this PR; the body seems to imply it 
fixes cases where parentheses aren't being added to preserve precedence, but 
I'm fairly sure we already have this code? Especially judging by the discussion 
on #16054
   
   Moreover the example in the PR body is incorrect with the behaviour of this 
PR:
   
   > After:
   > ```
   > > select (1+2)*3;
   > +------------------------------------+
   > | (Int64(1) + Int64(2)) * Int64(3)   |
   > +------------------------------------+
   > ```
   
   I tried out this PR with cli and the parentheses aren't added because this 
is a schema name. And there is a test added in this PR contradicting this 
statement.
   
   Could you help clarify what exactly this PR is achieving that we don't have 
on main?
