[postgis-users] Split Multistring on the_geom

Sorry, I didn't explain myself very well, now I can:
I don't need in every vertex a point or a node. I want to rebuild my
geometry by adding new nodes where I need.
This is the logic that I want in pgsql code:
1. Read over all the multilinestrings that I have, all the_geom in this
case,(Is really neccesary to explode them into linestrings?)
2. By default the first point will be the start node, and i will store it in
position, when I stop in a vertex, ask to postgis If there's an
intersection, if there`s one, store it in position, if there's an actual
node (will be the end node), store it, and close the multilinestring.
3. Repeat that process on the next node.
Thank you Nicolas.
