ST_CoordDim(geometry) gives 2 for 2D coordinates, 3 for 3D coordinates.
If you want to use old commands like "dimension" with a recent postgis version,
you have to run legacy.sql that comes with your postgis installation. But note
the st_dimension and st_coorddim are different things!

Subject: Re: [postgis-users] How to use dimension(geometry) command
Hi,
I meant dimension(geometry) to know if my consulted data is 2D or 3D.
I found in the oficial documentation that if you use dimension(geometry) you
get 2 for 2D or 3 for 3D data.
Do you know something about this?
Thanks,
José María
