Wildcards in GROUP BY?

Hello-

Is it possible to use wild cards in a GROUP BY statement?

ie: running the following query

SELECT a.*, COUNT(b.something)
FROM a, b
WHERE a.id=b.id
GROUP BY a.*;

returns the following message:
ERROR:  parser: parse error at or near "*"

If you cannot use wildcards in GROUP BY statements, is the only solution
to expand "a.*" to all its constituent parts?  Ugh.

main_v0_8=# select version();
                            version
