These points make needless segments<br>

<div>Thanks for response<br>
The fourth proposition is correct for external but not
internal lines : ST_Buffer (ST_Buffer (the_geom), -0.1),
0.1 <br>
<br>
Look <a href="http://imagik.fr/uploads/75091" target="_blank">http://imagik.fr/uploads/75091</a><br>
Do you have an idea to solve this new problem?
