The following bug has been logged online: Bug reference: 2203 Logged by: Robert Hostetter Email address: [EMAIL PROTECTED] PostgreSQL version: 8.1 Operating system: CentOS 4.1 Description: Group by, suggested "feature" Details:
I'm sure this will be considered a missing feature and not a bug, I know I would. We are converting from MySQL to PostgreSQL, which is a huge project. But one minor irritation we've noticed is the group by handling in PostgreSQL. If you group by a primary key for a table, you still have to include all the other columns you SELECT from that row, even though its guaranteed uniuqe because its a primary key. I understand requiring the other columns when you aren't guaranteed uniqueness, but in cases of a group by on a unique column you shouldn't need to include the rows, its repetitive, and makes porting harder for no reason. Also on a similar note, you can't group by any column you don't select. ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
