Hi hackers, Below is a `case when` demo,
```sql create table foo(a int, b int); insert into foo values (1, 2); select case 1 when 1 then a else b end from foo; ``` Currently, psql output is, ```text b --- 1 (1 row) ``` At the first glance at the output column title, I assume the result of the sql is wrong. It should be `a`. After some investigation, I discovered that the result's value is accurate. However, PostgreSQL utilizes b as the title for the output column. Nee we change the title of the case-when output column? If you hackers think it's worth the effort, I'm willing to invest time in working on it. Best Regards, Winter Loo
