I created a 2D spatial point dataset in a PostGIS database.
Today I tried to load them into FME, that works perfect. I get the right locations including the according attributes.

I only get this warning:
Dimension metadata is ambiguous for spatial column 'geom'.  Reporting 3D when 2D+measures might be present

Did I forget to set some specific settings while creating this dataset? There should be no 3D data present, I only saved 2D data :)
