Comment (by strk):

 I'm thinking if such handling of M is any useful :/
 Would using the CPA distance (closest point of approach) be too narrow in
 your opinion ?
 That'd be, only consider points having the same M as valid candidates for
 being "closest points" (ST_ClosestPointOfApproach gives you the right M
 for that)
