Mats,
Maybe the thing to do is to use the below function...?
GEOMETRYCOLLECTION(POINT(2 3),LINESTRING((2 3,3 4)))
Then inside the Geometry collection, you can put both a Polygon and a
Curve Polygon ?
I don't think that would render correctly in e.g. QuantumGIS, though.
Also, a polygon consists of closed rings. Therefore, it would not work.
This webpage seems to be a good place to read about all the different
types of shape you can store... though I guess you've seen it
already...

Hey Mats,
I'm just a newbie, so don't really have an answer for you I'm afraid,
but if a Polygon has a curved line, then it isn't a Polygon I don't
think. Polygons have only straight lines.
Yes. My internal polygon objects (for a corporate gis system) may contain
both, though, and I need a way to store them in PostGIS.
Am quite curious what the answer is to your query though... ! Good luck.
James
Thanks! :)
cheers,
Mats

Hi,
I have to deal with Polygons which have curves as well as straight lines.
How should I store them in postgis? (If I understand the documentation
correctly, Polygon is for linestrings, CurvePolygon is for
circularstrings,
but none of them handles a mix of both..?)
