work as it should on st_touches(line,point)

Nicklas -- I think this is by design.  Touches is a weird thing -- but in  
the docs it
says

2 geometries only touch if their boundaries share points together.  The  
boundary of a
line string is a MULTIPOINT.  If you do this

SELECt ST_AsText(ST_Boundary('LINESTRING(0 0, 1 1, 0 2)'::geometry))

you get this -- MULTIPOINT(0 0,0 2)  -- so the only geometries that qualify  
as
touching this linestring are 0 0  and 0 2 as you have observed.

Kevin please correct me if I am wrong because this is a very touchy subject  
(well in
terms of nuances anyway)
