[postgis-users] postgis 1.4 and curves

[Mario Jurcevic]

Hello,
postgis 1.4 has suport for curved polygons that is great, but not the
functions like st_union,st_intersection.
Is planned that this functions will support curves?
I tried a workarround transofrming curves to lines with:
set_union( st_linetocurve( st_curvetoline(the_geom) ) ) but the resulting
geometry has arcs modified in a strange
way, it always add a little segment at the beginning or end of the original
curve.

Maybe a bug in st_linetocurve?

Thanks

Mario
