> Currently, updating a cursor's column marked FOR UPDATE will fail if there is a generated
column based on it which is not marked FOR UPDATE.
>   ij> create table T(col1 int, col2 int, col3 generated always as (col1+col2));
>   ij> insert into t(col1,col2) values (1,2),(3,4);
>   2 rows inserted/updated/deleted
>   ij> get cursor c as 'SELECT COL1 FROM T FOR UPDATE OF COL1';
>   ij> next c;
>   COL1      
>   -----------
>   1          
>   ij> update t set col1 = 5 where current of c;
>   ERROR 42X31: Column 'COL3' is not in the FOR UPDATE list of cursor 'C'.
