[postgis-users] st_collect et st_union - multipart geometry

[Guillaume ARNAUD]

Hello,

 From a series of continuous lines, I must join them to have only one. 
With St_collect or st_union, it joins the lines in any direction and 
therefore creates multiparts for me. Is there a way to avoid this?

Thank you.
