The layers display with no issues in QGIS 2.0. After dumping the layers to shapefile using pgsql2shp, the shapefile can be added to QGIS 2.2 and it will display. Also, converting the geometry to 2d (using ST_Force2d) results in the layer being visible in QGIS 2.2.
I did not have data available to test whether the same issue affects 3dm or 3dz data from PostGIS.

- Priority changed from Normal to Severe/Regression
Just a me too: I have a couple of postgis tables that are not visible in 2.2 (they were in previous version).
The tables have column MultiPolygonZM
In the logs I see (might be unrelated though):
rc/core/symbology-ng/qgsrendererv2.cpp: 362: (renderFeatureWithSymbol) feature 89: unsupported wkb type 0x800007d6 for rendering
After changing geometry to 2D with ST_Force_2D the layers becomes visible again.
This is the query I used:
ALTER TABLE prg_tutela ALTER COLUMN geom TYPE geometry(MultiPolygon,32632) USING ST_Force_2d(geom);

- Status changed from Closed to Reopened
- Target version set to Version 2.8.2
Reopening as this table does not load in any of 1.8, 2.4, 2.6, 2.8 and master barnches:
CREATE TABLE t (g geometry); INSERT INTO t VALUES ('POINT(0 0 0 0)');

Note that enforcing a coordinate dimension constraint so that geometry_columns."coord_dimension" returns 4 is not enough by itself, but it also takes geometry_columns.type to be != 'GEOMETRY' for QGIS to force 2d. It would be very helpful to get a comprehensive testcase covering all combinations.
