You could use the OGR sql query option to wrap your geometry call in a force2d
or force3d function call in PostGIS?

Hi there.
I’m trying to figure out how to read xyzm geometries from postgis with ogr2ogr,
if at all possible.
I get the usual "is not supported" error:
ERROR 1: Reading EWKB with 4-dimensional coordinates (XYZM) is not supported
But reading old tickets I get the idea there is a way to read and just ignore
the 4th dimension, instead of getting null geometries.
For instance:
http://trac.osgeo.org/gdal/ticket/1323
From 8 years ago(!), says:
The problem does not occur if a layer is accessed using
OGRPGDataSource::GetLayerByname()
Then, geometry is read in EWKT form and parsed correctly without any errors but
M coordinate is omitted.
Can this be done using og2ogr?
Thanks,
Duarte
