[postgis-users] Linemerge roads

My layer contains a small number of linestrings that have a small Y, ie three linestrings two which share one end point of the third. How can i query to locate these, so i can manually delete them, or failing that do a st_linemerge to LINESTRING and have it basically ignore the two ends of the Y,  (or better still the shortest end).

TIA

Peter
