Is 320002120 in your spatial_ref_sys already ?
You'll need to assign it a different SRID, the spatial_ref_sys has provision
for "auth_srid" so you can put 320002120 in there and use something
valid for PostGIS' "srid" field.

Unfortunately we never got around writing a page about SRID ranges in
PostGIS manual (contributions welcome!) but the idea is that you put
your "custom" entries somewhere from 910000 and below 999000.
