Thank you
But your query merge two contiguous lines but not 3 or more contiguous lines...

Does this look correct?

select st_linemerge(st_collect(cs1.the_geom))
from (
        select the_geom, st_startpoint(cs_s.the_geom) as linepoint
        from mylinetable cs_s
UNION ALL select the_geom, st_endpoint(cs_e.the_geom) as linepoint
        from mylinetable cs_e

) as cs1
group by linepoint
having count(*) = 2

Hi

Is there a way to merge lines that are contiguous but stop merging at an intersection?
I have join an image.
Thank you
