Two ways to do this are
- import with osm2pgsql and a custom .style file and use and postgis 
intersection queries
- import with pgsnapshot and no linestrings and find nodes in common

The two differ in the case of a bridge where the roads cross but are not 
connected

Doing something with Nominatim has the advantage that it already has 
logic for handling inexact matches.
