Yes, it's supported.
test=# SELECT GeometryType(geom), NDims(geom), ZMFlag(geom) FROM
(SELECT 'POLYGON((0 0 10 1, 0 1 10 2, 1 1 10 3, 1 0 10 4, 0 0
10 1))'::geometry AS geom) AS foo;
summary | ndims | zmflag
---------------------------+-------+--------
| 4 | 3
Polygon[ZMB] with 1 rings
ring 0 has 5 points
(1 row)
How are you retrieving the vertex data?

greetings - I'm wondering if the 'Measure' stuff works at all for
Polygons. I'm trying to associate a Z value with each vertex of a polygon
(restricted to triangles for the moment.
I AddGeometryColumn with a dimension of '3', etc, and am able to insert
points that indeed have a Z. Things are GiST indexed properly, etc.
But I don't seem to be able to retrieve the vertex data with the Z
value...is this supported for polygons? I'm trying to cast things to
'PolygonM', etc; still no luck...
thanks!
