Not to mention transform support. Last I tried you can't transform circular strings.

I checked latest but there is limited info there. This is a great post but I don't think anyone answered it. http://postgis.refractions.net/pipermail/postgis-devel/2007-September/00 2778.html I would love to add this to the asSVG since SVG handles circular arcs. Where are we on the other issues for support (i.e area(), psql2shp, length(), etc.)? Thanks!

I need to store an Arc into a postgis database. As far as I know, Postgis doens't support arcs. Is there another way to convert a Three Point Arc to a MultiLineString?
