[postgis-users] Splitting linestring into line segments

[Rainer Spittel]

Hello,
 
  I like to split a linestring geometry with several points into a
number of 2 point line segments. I want to use those line segments to
measure the length of each individual side of a polygon/linestring.
 
  Before writing a function which iterate through each point in the
input linestring and create a set of 2 point lines, is there a better
way of archiving the same result?
 
Cheers
Rainer
