Indeed, my data presents some lines with less that 3 vertices, see the
screenshot below :

I will probably use python to make all my tests in order to generate
polygons when possible. - since I'm not confortable enough with postgresql
to handle that.

I guess it is possible to adapt the query (in first post) to test if at
least 3 vertices are there.
Or maybe I could adapt the nn_search() function to be sure the closest
vertice is connected to others.
