Hello,

I have a table with a polygon - typ. There I stored, for instance this
polygon:

test_db=# select * from geo where id = 1;
 id |             koerper
----+---------------------------------
  1 | ((0,0),(0,2),(2,2),(3,3),(5,0))
(1 Zeile)


Now, I need the area, but 'select area(koerper) from geo where id=1;'
fails. If I do 'select area(box(koerper)) from geo where id=1;' it
works, but this isn't the right answer. Is this a limitation for area()?

Version is 7.4.5.


Regards, Andreas
