Done, but I noticed while testing that it's not real consistent:

regression=# select xmlelement(name foo, 'infinity'::timestamp);
ERROR:  timestamp out of range
DETAIL:  XML does not support infinite timestamp values.
regression=# select xmlelement(name foo, xmlattributes('infinity'::timestamp as 
bar));                   
      xmlelement       
-----------------------
 <foo bar="infinity"/>
(1 row)

Should we consider doing something about that, or is it okay as-is?
