[UDD] debversion type does not work with MAX aggregate function

[Andreas Tille <andreas@an3as.eu>]

Hi,

if I try for instance

 SELECT  MAX(version) FROM packages WHERE package = 'gcc' GROUP BY version order by version desc;
    max     
------------
 4:4.3.3-5
 4:4.3.3-3
 4:4.3.2-2
 4:4.2.4-5
 4:4.1.1-15
(5 rows)

I get several maximum versions of the package gcc.  Am I missing something
or is there a problem in the debversion type implementation?

Kind regards

       Andreas.
