    Description

      I'm seeing this on head of trunk:

      ij> select c, c = all (values 'Y'), case when c = all (values 'Y') then true else false end from (values 'Y', 'N') v(c);
      C|2    |3    
      -------------
      Y|true |false
      N|false|true 
      
      2 rows selected
      

      Column 2 and column 3 should have the same value, but something seems to go wrong when the quantified comparison is used in a CASE expression.

      I'm seeing the expected result on 10.10.2.0, though:

      ij> select c, c = all (values 'Y'), case when c = all (values 'Y') then true else false end from (values 'Y', 'N') v(c);
      C|2    |3    
      -------------
      Y|true |true 
      N|false|false
      
      2 rows selected
