[postgis-users] Closing polylines

[georgew]

Hi Nicolas, thanks for your help. I don't think I am getting the same results
as you. In answer to an earlier question of yours, I have attached a small
(328K) zipped subset of a contour file with a representative set of the type
of shapes found in the full size one, but when I apply the sequence of code
in your post above, I get very little useful output. But I might doing
something wrong.
G.
