GROUP BY Wildcard Syntax Thought

When specifying columns in a GROUP BY clause would it be possible to use a
wildcard to specify all columns coming from a given relation?

SELECT

rosum.*,

sum(ld.amount) AS ldcost,

count(ld.amount) AS ldcount,

rosum.rocost + sum(ld.amount) AS netbal

FROM (

SELECT w.s_id, w.accountnumber, w.date_reference, w.invoicenumber,

sum(w.amount_cost) AS rocost, count(w.amount_cost) AS rocount

FROM wiplaboradpstaging w

WHERE <FILTER>

GROUP BY w.s_id, w.accountnumber, w.date_reference, w.invoicenumber

) rosum

LEFT JOIN ledgerdetail ld ON (

rosum.s_id = ld.s_id AND

rosum.accountnumber = ld.accountnumber AND

rosum.invoicenumber = ld.reference

)

GROUP BY rosum.* < ------- WildCard Group By Since the rosum sub-query has
already been subjected to a GROUP BY

Attempt to run this query in 9.0.3 results in:

"SQL Error: ERROR: column "rosum.s_id" must appear in the GROUP BY clause
or be used in an aggregate function

LINE 2: rosum.*,"
