 When trying
 SELECT ST_AsText(ST_centroid(geom))
 FROM st_geomfromtext('circularstring(0 0 , 1 1, 2 0)') as geom

 Error is:
 ERROR:  Exception in LWGEOM2GEOS: curved geometry not supported.


 Centroid of such a curve would only be
 centroid(ST_DumpPoints(circularstring))
 , so maybe easy to add?
