[postgis-devel] ST_GeometryType output is this right?

[Paragon Corporation]

I was doing some tests on ST_GeometryType and noticed it just returns
ST_Geometry for CurvedPolygon and CircularString.  I thought these are
supported in the SQL MM specs so why does it return a generic when the old
returns something more meaningful.

So not sure if this is a bug or by design?  Same behavior for both 1.3 and
1.4

Example:

SELECT ST_GeometryType(geom) As newname, GeometryType(geom) as oldname
FROM ( VALUES (ST_GeomFromText('POLYGON((-0.25 -1.25,-0.25 1.25,2.5 1.25,2.5
-1.25,-0.25 -1.25),
(2.25 0,1.25 1,1.25 -1,2.25 0),(1 -1,1 1,0 0,1 -1))') ),
( ST_Point(1,2) ),
( ST_Buffer(ST_Point(1,2), 3) ),
( ST_LineToCurve(ST_Buffer(ST_Point(1,2), 3)) ) ,
( ST_LineToCurve(ST_Boundary(ST_Buffer(ST_Point(1,2), 3))) ) 

 ) As foo(geom);

Gives me:

   newname   |    oldname
-------------+----------------
 ST_Polygon  | POLYGON
 ST_Point    | POINT
 ST_Polygon  | POLYGON
 ST_Geometry | CURVEPOLYGON
 ST_Geometry | CIRCULARSTRING
