[postgis-users] get segment of multiline between two points

[Paragon Corporation]

Marco,

Yes.

If you are using PostGIS 1.5 or above you can use ST_DumpPoints to dump the
points out which is a bit faster than ST_PointN (or you can use ST_Point)

http://www.postgis.org/documentation/manual-svn/ST_DumpPoints.html

For lower versions you can use ST_PointN
