Transform is returning to the same value, for different inputs?  Below is what I have \
done...  
select AddGeometryColumn('data_stage', 'table', 'geo4269', 4269, 'POINT', 2)
select AddGeometryColumn('data_stage', 'table', 'geo32107', 32107, 'POINT', 2)
 
update tableset geo32107= setsrid(MakePoint(x, y), 32107) 
where ....
 
update table set geo4269 = transfrom(geo32107, 4269)
where ....column geo4269 all have the same vaule.  select AsText(geo4269) returns \
'POINT(-115.583333333333 90)' for all rows.  And select AsText(geo32107) returns the \
point as input.  
Am I using transform wrong?  Or any other problems?  Any help many thanks...
