I'm not sure if it's a bug, but when I try to st_difference self
intersected line I'm getting line additionally divided also in a point of
self-intersection.
Example:
select ST_AsText(ST_difference(aa.geom,
ST_Buffer(ST_MakePoint(-79.3226028055573, 43.7717938393679),0.00001)))
from (select ST_GeomFromText('LINESTRING(-79.32193761772157
43.77267702526523,-79.32157820171358 43.7718287022164,-79.3214011759186
43.77199526887857,-79.32260280555727 43.771793839367916,-79.32308023876192
43.771685377042715,-79.32367568916322 43.77158853551472)') as geom) as aa
