[postgis-users] Error ST_LineToCurve(geom)

[Davide Ticozzi]

Hi,
I have a serius problem.
 I'm calling St_LineToCurve with the geometry attached, but returns me 
"geometry require more points"!
The geom is a linearized arc, and I think that the error occours when 
the function try to construct the circularstring.

Any idea?

Best regards
Dave
