Group By and wildcards...

[Jon Lapham <lapham@xxxxxxxxx>]

When using queries with aggregate functions, is there any way to not 
have to have to explicitly write all the columns names after the GROUP 
BY ?  I would like to use a wildcard "*".

Imagine tables a, b, c, d each with hundreds of columns.

As an example, I would like to write:

SELECT a.*, b.*, c.*, SUM(d.blah)
FROM a, b, c, d
WHERE <some join conditions>
GROUP BY a.*, b.*, c.*

Instead of having to expand the "GROUP BY a.*, b.*, c.*" using the 
explicit column names of all the column in a, b, and c.

This becomes a maintenance nightmare as you add/drop column in these 
tables...

Thanks for any advice on how to handle this,
-Jon

PS: I'm using postgresql v7.4.x
